When was the last time you did something nice for someone? What was it?

The last time that i remember doing something nice was helping my friend Jonah with his apartment project that he didn't even start and was due the next day and the teacher gave them a whole month to do it so we spent about 4-5 hours working on it. We had to list all the elements on  the periodic table that would be inside his apartment, like what everything in the apartment was made out of and stuff. We had to organize the data and list the quantities of each. Jonah wrote the reflection essay on it but when we got it all done, it felt great to help my friend finish his project. The next week he came to me saying he got a 100% on it so we did good work & not slacker work for it being last minute.
