The meanest & nicest thing anyone has ever said to you

As the topic suggests, what are the meanest and nicest things anyone has ever said to you? While knowing who said it may be nice, you're not going to be forced to in any possible way. But it would be nice if you said if the person was someone you know online or offline... :x

Both were from my ex-senpai

"You're like the brother I never had. Arigato, Kimo." ~ Three years ago
"The only reason you got to know about me was from a third party, not from me directly. This is just how much I trust you." ~ Seven months ago, over the "accident".

Aside from that, I remember the second nicest thing being from Nour, though I can't remember what it was.

Nicest: "You mean the world to me."
Meanest: "I hoped your brother would be here, he would get the job done, unlike you."

Meanest: something about it will always be my fault if something goes wrong and i was involved.
cant think of nicest

Nicest: "Apparently, you're very attractive"
(This is in teh context of a party with a guy:girl ratio of 10:50, and having been talking to one particular girl I was hooking up with, my drunken friend at one point walked past me and said that to me. Apparently they'd been talking about who the hottest guy there was.)

Meanest I'm not quite sure about. I don't really take these things seriously.

Jj told me something lewd ...applies to both

Nicest: "You're so stupid, you always think of me first. I mean I really like it but..." -the day I was convinced my gf was a tsundere

Meanest: plenty of things from my dad, but I'd rather not write them down.
