I have a couple that seem to stand out for me.
For many years as a kid, I got to go to the Christmas party that the factory my Dad worked at threw for the kiddies. They always had a movie, candy, cookies, and of course, Santa Claus was there to listen to your begging wish list....and then one of his cute young babes elves would give each little monster kid a wrapped present to take home. The presents were always really nice (not cheap crap) toys or games, depending on the kids age.
The second one that stands out, was Christmas of '68....Grandad gave me a super, neato, coool train set!!!
It had a Santa Fe loco, cars, and caboose, and a small oval of track! The reason that one stands out, is because that ol' train still runs on my model railroad layout...but instead of a mere small oval, it can traverse about 300+ feet of track. It grew from a $29 train set, to a roughly $15k (so far) hobby.
We still have some of the games from those early parties, and I'll be spending ALOT of my FIRE time "Working on the Railroad"!!! I'll be Choo-Choo Charlie Goonie! :
