I have a tendency to take things too far sometimes... people have occasionally told me I offended them, but they wait until months later to tell me for some reason, instead of just telling me to shut up when I'm being an ass. I mean, I'm constantly joking around, and I tease people all the time, so I don't know when I'm pushing it. Most of my friends are pretty thick-skinned, and they know I'm just trying to be funny (whether I succeed or not). But if I'm getting carried away, just say "that's enough, Ade," and I'll understand.
As for me, I haven't really been offended by friendly teasing... well, except one time in a writing group, this one girl I didn't like was teasing about something that makes me really uncomfortable, and I got pissed off and moved my seat. I also don't like teasing that involves a lot of touching. I mean, many of my friends and I will sit around and poke each other endlessly, and that's ok. But don't try to tickle me. Ever. I'm not ticklish, and I have sensory issues, so to me, tickling just feels irritating and painful (yes, it really hurts), and I feel like it's an invasion of personal space. And yet, I'm usually the one doing the tickling. I enjoy tormenting small children like that. And occasionally big children too.
