What's the most ungrateful thing someone has done to you?

jagex banned my runescape account.

Lent my DBZ 1 manga to my friend and sold it to someone. Keep in mind that this was the blue cover edition or however you shall classify it, not the Shonen Jump one. :/ Clicky

Many years ago my cousins and I were playing cricket on the roof, I had just brought a sandwich from below and put it aside on the table to eat a bit later after playing my turn, unbeknownst to me a crow flew near it and flew off with it the whole thing as I helplessly gave chase for a few meters.

I had a friend. He was my best friend. We played almost every day and had fun (For like 8 years). Then he just started ignoring me and he still ignores me :(

i had a latin teacher who yelled at me considerably because i was "staring" at him

not the most ungrateful thing, but it's in my recent memory

it didn't happen to me, i did it (and i still feel terrible about it). I had met this girl that was new to my area, and EVERYONE liked her, i was one of the lucky few who became good friends with her. well she ends up going out with (insert generic name here). months into their relationship, we are talking through skype, and after a little bit of talking, the subject comes up to who likes who, and i had told her that I liked her (i really did). After telling her about that she started talking about how she would have never gone out with (boyfriend) if she had known. she and her BF fight and within days they break up with each other.(and i assume it was so she can go out with me). right after that conversation, i somewhat block communication with her and we have only spoken once more in between then and now. i cant help but feel terrible because she broke up with her boyfriend to go out with me and then i kinda just leave her, also, her ex was one of my closest friends.

Walked home 1 day after my Computer Course finished. 2 guys crossed the street, walked up to me, and asked me for my wallet. I said no, so they grabbed me, and punched me straight down, punched me some more, and took off with my wallet and my bag.

I was friends with a guy for about 2 years, I was always there to comfort him when something rough happened and once stayed up all night because he was suicidal and I wouldn't go to bed until he assured me he was feeling better. Then when I was in a relationship, he was actively sabotaging it by making lies to my boyfriend. When I broke it off, he made sure to gloat about it to see my reaction. I haven't spoken to that person again and wouldn't even if he apologized.
