Pretty much every argument I've ever gotten into...
Trouble is, I haven't learnt my lesson. Only thing is, now I start on one with someone, and kind of give up halfway through. (as in, at some point I won't even read what they've said in reply).
Doesn't even matter if the argument is about something serious or trivial, whether it's rational or just stupid, whether it's a calm, reasonable discussion or a series of stupid, mindless rants...
But... Yeah, I wouldn't want to see much of any of it back...
Also sometimes I get the feeling that I say things that are racist (not blatantly so, but you know, in very subtle, technical, hard to follow kind of ways.), or very judgemental and dismissive of certain groups (ironically, 'professionals' in certain fields. Especially medical or psychology in particular)
That... Is always particularly cringe-worthy to see back after the fact...
Oh, while I'm at it, (and fortunately this tends to happen more in private messages, but it sometimes spills over into other things), this really weird, twisted kind of flirty behaviour I seem to have sometimes. Especially cringe-worthy in how oblivious I am to what I'm implying sometimes. (Or that when I do notice I sometimes run with it. Not sure which is worse... XD)
That uh... That gets weird. XD
