My son blew up his sister’s Barbie with a firecracker. I’d suspect the boys had stolen one of their sisters’ dolls and were doing this to torment her and they thought it was funny. They probably didn’t even think of the “race” of the doll. Brothers can be a serious pain in the neck!
And yes, my son grew up to be perfectly normal and is not a psychotic killer. He took teasing a little too far...
Looks like you and I still remember what it was like to be kids and see the world through a kid’s eyes and brain. :)
FWIW, I’m 64 and my brother is 63. He was more of a teaser and he still, to this day, teases too much. i.e. he doen’t know when to quit and it’s not funny. We all have our weaknesses, though.
