<human>: Can you succinctly summarize the text in 1-3 sentences?

Today, during school, three friends and I were walking through the school when I spotted an envelope on the ground. I rushed over to it before someone else could pick it up because I saw what looked like a check in it. It was. There were 2 checks for $20 and three $20 bills. $100 in total. My first thought was, we need to turn this in. There was a check in it, so we could identify whose money it was. When we got to the office, we gave the person at the desk the envelope. The person told us we were such good kids and we should be rewarded. She took our names and thanked us once more for turning in the money. In homeroom, during the morning show, they showed text on the screen thanking the kids who found the money and turned it in. They also announced it over the intercom. The girl who lost the money was in my home room. She thanked me and gave me a hug. The money was for a fundraiser for the softball team. It felt pretty good to do good. Then, during 5th period, I was called down to a certain teachers room. It was the softball coach. He thanked me and told me he wanted to find a way to reward me and my friends for turning in the money. He said he was going to give us each a softball t-shirt. (He called us all in at once, but we aren't all in the same class during 5th period, so we had separate conversations with him). I said ok (so did my friends) so we are all getting softball t-shirts. Some kids in my classes called me dumb for not taking the $100 and splitting it up between us four. I just ignored them.

Also, I'm 16 in high school.
