I’ve done this.
I’m the cousin you can only stand for short periods of time.
Nosy sister-in-law who cannot resist trying to matchmake you. Really, it’s a horrible thing, but I cannot resist.
The nice, quiet, boring Uncle who talks to the kids like they’re adults. And, doesn’t think matchmaking is a bad thing, if the matchmaker is GOOD at it. 
Stay of my lawn, ya rotten kids!!
I’m the weird cat lady down the street. All the kids egg my house on Halloween. Animal control stops by about once a week to make sure all 27 cats are properly cared for.; occasionally they confiscate a few. I never keep real human food in the house; just Whisker Lickins. If its good enough for the cats… its good enough for me. (Besides I’m on a fixed income.) Everyone on the street thinks I’m a witch. My house needs paint, but the garden is perfect.
i’m the strange neighbor who doesn’t socialize terribly much. i work on my flowerbeds and potted plants and herbs, and other than that am rarely seen. i go WAAAAY overboard on Halloween…kids come from neighborhoods far and wide to oooh and aaah over all the scary props i have set out.
you know…the type that would paint a pentacle on their door if they knew the Jehovah’s Witnesses were working the neighborhood.
is there an evil grin smiley?
lachesis
Oooh…homemade walnut banana bread? Mr. Butrscotch is at work, come on over, ** astro**!
I’m the guy who waits just long enough to not be overly rude, but is still the first one to get a second helping of the good stuff that everybody wants, but are afraid to be the first to get a second helping of.
I’m also the ‘If anyone was going to have a bunch of dead bodies in the basement I’d have thought it would be him’ guy
I’m the kid running around the adults feet playing and having fun. Occasionally surprising people with how much I really know I can interact with the adults and the other kids, and I’m not afraid to ask questions if I don’t know the answer. For the most part I’m well mannered, but I avoid the aunts who’ll pinch my cheeks and tell me how much I’ve grown since I was a baby because I don’t remember them and don’t want to have my cheeks pinched.
Oh I also love my Uncle Sunspace because he’s cool and plays lego’s with me 
“Enki? Isn’t he that weird guy that lives in that old shack in the woods?”
“Don’t talk about him. There’s something Not Quite Right with him.”
Little do they know, that my 250 square foot clapboard shack has a 1400 square foot finished basement, with a pool table, hot tub and fully stocked wet bar.
I’m the neighbor who everyone likes. I’m friendly and enjoy doing favors including baking for no reason in particular other than I thought that it’d make someone happy. Though I don’t get out to say Hi too much as I tend to be busy with family matters, that and no one really likes my misanthropic husband.
I’m the new neighbor who hires your 17 year old kid to mow my lawn, and figure you owe me one because he just mowed over my herb garden and STILL expects to be paid! So I pay him.
I’m also opinionated, everything is black & white, and use my past failures as justification for my advice on anything. As much as you hate to admit it, I’m usually right. Cute, but standoffish. I play well with others as long as they play what I want, but if I have to play their games, they’d better cut me slack on the rules.
(What’s interesting is the number of people who prefer to be neighbors, and not actually members of this “family.”)
I’m the laid-back, friendly sister, not as worldly as some of the more mature folks, but always has an open home to the family and friends. Everyone comes to hang out and talk about what everyone else is doing, and have a beer and play darts.
The key’s under the mat, so let yourself in!
(Oh, and Cooler, you’re fitting in just fine, and you amuse me, anyway. Welcome!)
I’m the never married middle aged brother that the family thinks may be a little " “funny”, if ya know what I mean." I tell everybody the guy living in my house is my “roommate.” We’ve been “roommates” for twenty years.
I’m the cousin that bakes chocolate chip cookies for everyone, especially the kids, who’s job involves physics, but no one quite understands exactly what I do.
I’m the bald uncle with the lame jokes.
I’m the cousin who is away at school and is really terrible at keeping in touch with the rest of the family. I’m also known as the perpetual/professional student because I’ve been at various colleges for close to 10 years and still don’t have my bachelor degree. But some day I’ll make you all proud!
I’m your grouchy uncle. Your Mom and Dad love me, but you never thought I paid much attention to you. Then when you got married, I sent you a wonderful, thoughtful, unforgettable present and you realized I had been paying attention all along. But I’m still grouchy.
Guy on the couch.
I’m going back to sleep.
