How do you react to being teased or made fun of?

it's fine once in a while, but repetitive is bullying behavior.

I either don’t react or I laugh it off. Depends on the circumstances. When I was younger and made fun of more often, I stopped reacting and they got bored.

Probably agree with them

It's the past. And it doesn't determine who you are as a person. It's over, try to enjoy your life in the present.

If it’s one to one I might believe it’s just joking but if there’s an audience it feels like put downs.

I'm the youngest, with an older brother and an older sister.
I got used to it.

If it happens in real life, I try to walk away from those situations. If it happens online, I try make fun back - not by getting into an insult trading contest, but by ridiculing what they've already said. And if they throw insults I make fun of their inability to debate.

I take it as banter

I usually turned the tables, I could insult myself better than they could.

I'm really thick skinned about things like that.

Generally, not well. It depends on who it is and how do they tease me. Putting others down has always been my brother's past time activity. I always wished I could found appropriate words to retort back but it's not in my nature to constantly think about ways how to insult other people so as a short-tempered person I used to resort to physical violence. I'm genuinely glad I don't have to deal with that shit anymore. A bit of a banter is fun but not when you just know the other person feeds on your annoyance. That's just fucked up.
When I'm teased by random people on SW or someone who don't show bad intentions I usually laugh or roll my eyes.

Internalize it for the rest of my life
