I don't see anything wrong with sarcasm.. and I don't think of it as like something you learn like a joke.. it's just a personality quirk. Some sarcasm is different than others I guess, so maybe some are worse. I'm sarcastic, but that's just my personality and always has been. I've never seen daria.. I don't have cable and never have had cable.
Also I don't care much for just regular joking.. or playing tricks on people. Some harmless joking isn't so bad.
I notice that more than sarcasm.. actually I can't think of many people I've come across that have been sarcastic. Most people aren't. Most of the time sarcastic remarks are made towards something that might already be a bit silly.. all in all it's funny and pretty noticeable.
The sarcasm that really is just mean comments.. isn't sarcasm, that's just mean comments. I knew a girl like that before.. and they really weren't sarcastic remarks.. there was no sarcasm, it was just being annoyed at things and saying mean things. I don't know how to explain it, but sarcasm is something that isn't done all the time and is directed towards something.. just random mean remarks about stuff isn't sarcasm... I don't know how to explain it, but I think sometimes people say something was sarcastic when it wasn't.
Like this one guy I was friends with.. he used to say he was really sarcastic, but he really wasn't. Maybe he made a sarcastic remark a few times, but overall he really was never sarcastic. He was over the top, silly, said he could be mean or say mean things, but over all at the most he made jokes that didn't make sense and weren't funny and nothing was sarcastic. If it was, it was by accident.
