Kindest thing iv'e ever done for someone? Does it count for putting my life on the line to put their garage fire out? Other than that I can't thing of anything really nice i have done for anything other than just holding doors open for random people, and helping them carry heavy stuff at work. I have helped people with their homework, helped them figure out relationship stuff which is weird because i have never been in a relationship so i don't know how i helped them through anything that i have no knowledge of. Those are all nice things but i am not sure what the nicest thing i have ever done is. Lol
