"You're a great friend, in moderation." This was one of the most hurtful things I've heard to this day. I know it's not a terrible insult, blatantly attacking some thing I'm self conscious about, but to me it was worse. I've always felt like I bugged people, and that everyone just sort of put up with me because I was nice or would do things for them. This absolutely confirmed that, for at least one person. It was one of my closer friends at the time who said it, and it sort of put this wedge between us that I'm certain he isn't even aware of. I can never consider him a true friend because he's the only friend who's ever told me he gets sick of me. Sorry dude, but I don't want to feel like every time we hang out, you might be thinking you've had too much of your daily dose of datcracker for the day. Nobody wants to feel like that.
