Summary: John needn't have worried.
Kiss-Chase by frostygossamer
The wee Winchesters are at a kiddies' party.
Sam is 4 years old and one of the neighbour's little girls has become a firm friend of little Sam in the couple months that they have been in town.
Today is her birthday and Sam and Dean have been invited. John has come along to just to see his boys have a normal good time for a change. And to make sure they don't let anything slip about what they're up to here. He always has to be wary. They're only kids after all.
After candy and Jell-O and "Happy Birthday to You" and big wedges of birthday cake they were now playing party games.
All the kids are screaming and running around like excited puppies playing "Kiss-chase".
It's all fine until, when he gets tagged, Sam runs up to Dean and plants a big sloppy kiss on his lips, then shouts "You're it! You're it!".
Dean protests volubly, wiping his mouth, in an exaggerated way, with his sleeve, all affronted 8-year-old big-brother dignity.
The other kids laugh and Sam is confused. He begins to blub.
John pulls him aside and hunkers down to the child's on eye level.
"Why did they laugh, Dad", Sam sobs.
"Poor kid!", thinks John. "He hardly ever gets to play with other kids. He doesn't know how to behave".
"Cos you broke the rules, son", he tells Sam quietly.
"S-Silly game", Sam stutters. "Don't know the rools. Nobody told me".
"Well, the rules are: little boys kiss little girls, or little girls kiss little boys", John explains slowly. "And sometimes if there are no boys little girls kiss other little girls. But little boys NEVER EVER kiss other little boys".
"Them's stoopid rools, Dad", Sam whines.
"Yeah, well, them's the rules, Sammy my boy", John confirms, patting him on the head.
"Little boys don't kiss little boys?", Sam repeats, wiping his eyes. "Even when it's Dean?".
"No, little boys never do that, not even when it's their big brother", agrees John.
Sam analyses this information for a moment.
"So, when I'm a big boy will it be OK to kiss other big boys?", he asks with innocent logic.
"Well", John pauses. Now John is a man's man and he agonizes over his reply. "What am I gonna tell him now?", he thinks, "You gota move with the times, I guess, 'Political Correctness' and all".
"I guess when you're a big boy you can kiss who-the-damn-ever you want" Then he laughs, "But you'd better not try it on Dean again. He doesn't like it one bit!".
Oddly, 20-some years later, Dean did like it, and quite a lot!
The End
A/N: This popped into my head at the bus-stop. Now I had better get back to my studies or I'm never going to catch up!
