I'm sure my kids will chime in here, lol. 2 of them belong to my "Frequent Reader Club". (Hint...if you come out of lurkerdom(even just to say "Hi!", you too can be a member! *snerk*)
About 20 years ago (can it possibly be THAT long ago?) I purchased a set of plastic world placemats.
Our family resembled Roseanne Barr's family on her sitcom...very noisy, active, and going every which way ALL the time. Three kids in sports and one or two exchange students living with us each year made it quite lively. Even tho we were running at break-neck speed, we managed to sit together for dinner most nights. OK, dinnertime was 9pm sometimes, after a game or two or three, but we sat together nonetheless.
We used to play a game before, during and after dinner to challenge each other on the hidden places of the world. "Can you find __________ ?" Yes, you likely needed a magnifying glass to find this obscure location, but that was part of the fun.
I guess we have more family traditions than I realize, what do you remember of your childhood traditions?
