I think you’re overthinking it.
Hey, speak for yourself.
Seriously – my mom would piggy me at any age! She did the best wee-wee-wee-wee-wee-wee EVAH!
My dad still calls me by my childhood nickname - Scooter Bug - and I’m well into middle age. In fact, I’ve never heard him call me by my given name, even when he was mad at me. He even had my nephews calling me Aunt Scooter. Thankfully, they’ve grown out of that - but not until they were adults themselves.
Being stuck with Scooter Bug your whole life can be a bit of a challenge. I’ll have to tell my grown daughter “Stinker Butt” about that one.
My mom would say things like, “Shut up you little shit.”
And I would respond with, “Mom please stop hitting me.”
You kinda just made me tear up. My dad called me “punkin” since I was a little kid. He never stopped, and I found it oddly endearing. The last time was in 2013, shortly before he passed away.
I used to get piggyback rides from Mom, “for the sake of a song”, meaning for as long as it took her to sing a nursery rhyme, usually Four and Twenty Blackbirds…complete with her “nipping off my nose”. This continued our whole lives whenever we’d be in a swimming pool, with her pulling adult me around “for the sake of a song”.
This thread has made me smile and tear up too. My 97 year old Mom lived with me and every night I’d end with a “See you later alligator” and (if her mind was clear enough), she’d respond with “In a while crocodile.” Sometimes it was only “Croc…?”
She passed away day before yesterday. See you later Mom.
My condolences, brachyrhynchos.
I’m so sorry, but I am also happy you had a good long time with your mom. I used to wish I would get to take care of my mom when she was old. 
I’ve stopped reading this thread more than one time because it is so dusty. My dad was in the end stages of Parkinson’s and really couldn’t talk, but as I was leaving my final visit with him (also in 2013) my Mom leaned over to him and laughed. She told me he said “see ya’ later alligator.” I told him “see you soon dirty spoon.” Those were the last words we shared.
Damn dust… it’s getting bad in here.
That’s just rude. That’s not a girl’s nickname!! Stinkerbell is a much better choice :D.
(Moon Unit disagrees, for some reason :D:D:D:D).
