When I was a kid, it’d have to be Memorial Day. All the extended family would convene at the old family cemetery to decorate the graves. That isn’t the weird thing… the weird thing was we treated it as a family reunion and picnicked together among the head stones.
When I first met my wife’s family, they had a tradition of playing cards (Canasta) anytime the family would gather. My wife however didn’t know how to play. They taught me and it was actually really fun hanging out and bullshitting. Like guys playing poker. We still do it all the time after nearly 20 years of being married.
My sister did this with her ex-inlaws except it was Pinochle which they taught to me as a teenager when I was there on an extended visit. It was also pretty damned fun.
I wish my in laws were game players. My grandmother used to get us all to play Rook together. It’s like Gin Rummy but acceptable for Southern Baptists to yell out! … it was a dry county…
