I can't stop calling random numbers in Israel and ask ,"mein fuhrer" in an aggressive manner imitating an austrian accent.
Whoa, I hope you're joking! Why are you making those types of phone calls?
Because you're the only one who understands me.
It's not good to remind people of traumatic events. You should get help from a therapist if you feel the need to make light of someone's trauma.
I just do it for fun. Who cares? Plus I don't see any harm in it.
You may see it as fun and playful, but this could really hurt someone who had a traumatic memory of those times. What if their great grandparents were killed or something? You need to be nicer, or else you'll lose your friends.
