What's the nicest thing you've done for someone.
Just to cut away at the negativity for a second. Let me tell you mine:
Senior year of high school, prom season is starting to approach. Girls are getting asked left and right, and I've already made the decision that I didn't want to go. However, once the whole proposal phase was over, I noticed that this one particular girl still didn't have a date. I knew her for a long time and she was such a sweet person, but she was completely overlooked by every guy in the school. I remembered that she didn't have a date the previous year, either. I thought, "Going to prom is the highlight of most girls' high school careers. I feel bad that she has to go without a date again." After thinking about it for a few days, I decided to take her myself, even though I knew that I would absolutely hate the event. I asked her, and she said "Yes". I've never seen a girl's eyes light up the way hers did after I asked her. I knew she legitimately wanted to go with me and was grateful that I asked. Leading up to the prom, I noticed that she seemed much happier overall, like she came out of her shell. The event came... and it was just as bad as I thought it would be. Horrible music, obnoxious peers, and the popularity contest that was the prom king and queen. I had a horrible time, but she had an awesome time, and that's all I wanted. In hindsight, I think I did the right thing, even though the outcome wasn't the best. That was probably the most "selfless" thing I've ever done that I wasn't obligated to do.
