Let’s have some fun with this thread.
Please post something that the opposite sex (relative to you) doesn’t understand about your gender. Please also post your gender. For example, I would post:
Male here. Men are multitaskers. We’re usually listening to you even if it appears we aren’t.
Unless you’re sporting some serious cleavage. 
Male here.
Punishing us by giving us the silent treatment doesn’t work. To us silence is bliss.
The television is on. I’m awake. I’m watching it.
At this particular moment, I really don’t give a shit what Nancy said to you today.
Also, there’s a very fine line between reminding me about something and nagging me about it.
Male here: I’m not thinking anything, goddamnit.
Female here. Yes, sometimes I do really need to hear that I look nice twice. I don’t know why either, just put up with me when I ask you a second time, please 
Also, a clean space does not a dumping ground make.
For pretty much every situation where the opposite sex (female) doesn’t get me, the rest of my own sex seems to have a different take on it and would not ratify me as spokesguy for the issue.
The “visual aspects of sexuality” thing is absolutely very top of the list. The female sex generally doesn’t get our side of the experience, and guys do seem to be in agreement about that, but I can’t talk with more than a tiny handful of rare & unusual guys about it either. (And vice versa, I don’t get where most guys are coming from on it).
Male:
Yes, sometimes piling the mail [or clothes, books, laundry, etc] and sorting it later is the right thing to do.
Yes, I can have 5 projects going at one time, in varying degrees of completion, before we have to meet the neighbors for afternoon drinks, all to be completed backwards, and with out instruction other than what’s knocking around in my head.
The shoe thing. Yes, I really do need another pair of shoes. No, these shoes are not ‘just like’ those other shoes I already have. Yes, I have a spot to store them picked out.
*Lucky for me my husband gave up on this one very shortly after we met. Now he’ll actually encourage me to by shoes. Bit of an enabler, that one…
Male. We find the 3 Stooges funny. Yes it’s stupid and childish but it’s still funny.
And it’s funnier if our buddies are sitting on the couch saying “Woo woo woo” and “Nyuk nyuk nyuk” along with the movie and somebody laughs so hard that they fart.
Comedy gold.
You say “Oh, a wise guy, eh?” in a room full of 90 year old male accountants and one of them will ditch his walker to demonstrate the Curly Shuffle.
Please, please explain this. I own two pairs of sneakers, two pairs of dress shoes, and flip-flops. Why does anyone need more than that?
Women just don’t understand that we need our blow-jobs *before *the jacuzzi, damnit.
Am I right fellas?
Fellas?
Mel?
You’ve obviously never experienced the benefits of the f-me pump*.
*or boot, or sandal, or wedge, or…
Female here.
That thing you can’t find in the refrigerator? It is in the same damn place it was in last time. Have you ever noticed that the mayo is always, always, always in the door of the fridge on the middle shelf? There is a reason it is always in that same spot, so that hopefully I won’t be dragged away from my book to help you find the mayo.
…I’m confuzzled… It’s… underutilized space. Are you telling me I should pile things on top of each other… how could I possibly hope to add that in my archiving system?
Socks/whitish/almost clean: bedroom floor, grid reference 4 - 3
(or c1-1b-2-1.4.3 for short)
T-shirt/black/stiff but wearable: bedroom floor, grid reference 4 - 4
(c5-2-5-1.4.4)
I’d have to add a whole layer of coordinates to my system, to represent the Z-axes… and that could take months to implement.
…Apparently one of the things women don’t understand is the importance of order, and proper archiving procedure.
Another thing.
Ladies, your male friends want to sleep with you. Sorry you had to hear it from me.
Sorry fact about the human male animal. 
but true.
Dear men: When I am sad or upset, I do not want your advice. I am a grown woman with a masters’ degree and I don’t need your amazing expertise. Yes, I do want you to blow sunshine up my ass - thanks for asking! Yes - lie!
yup - it’s true. Glad that you differentiated me from the guys . . . .
That’s one I figured out all by myself, that and that when you talk to me about a problem, you don’t want me to try to fix it… you want to talk about it so you can decide what to do.
