Never said anything to anyone that was really mean. Someone told me once "I'd be very hansom if my nose wasn't so big" LOL I can live with that. you know what they say about men with big noses...
Even just in terms of looks, not anything else I think big noses look great on many/most men!! I mean, look at Liam Neeson, he has a large BROKEN nose and how attractive is he?! Yet another advantage men have over women, looks-wise
"You're going to study Russian??? You're not even fit to work at a supermarket, let alone learn a language like that?"
"You torment on purpose, not because you care about people/animals, but because you find gratification in it for yourself. You're selfish and lazy and have no discipline."
"Oh plz, don't tell me you're going to let a guy come inbetween us. For that matter, it's water under the bridge, I dunno why you're getting worked up about this :rolli:" (best friend after I found out she cheated on me with my SO)
"The amount of pain you've caused me and the cruelty you're capable of dealing to other people is incredible. And I have no clue why it is you feel the need to hurt me the worst possible way. It's like you get a sadistic satisfaction from it and I don't see this so called love you claim to feel for me."
"You're a psychopath."
Edit: Some comments stay with you forever, yes, especially those given by people you trusted, loved and respected.
I reacted to the insults with a combo of revenge and emo-hysteria (I was young still with most of those).
I don't take it well when someone says something like that to me. I need time to digest and process it.
I feel incredibly guilty when I say mean things myself, unless they've gutted me so to my utter core that I feel completely justified. I'll regret it happened, but not what I said or how I said it.
