When I was in college, I let German tourists take pictures with me in my graduation gown. Even at the time I thought it was weird. But since my college years, I haven’t allowed strangers to take pics of me “just because” here or abroad.
“Curiosity” means very little to me.
People on the clock app were saying in China they actually have been known to post pics of Black people on WeChat to make fun of them.
So, maybe not the best idea to let strangers take pics of/with you.
Anyway, I wish you all safe, joyous, and comfortable travels. You deserve to see the world in peace just like anyone else.
