What's the nicest thing anyone has ever done for you?

The nicest thing anyone has ever done for me was to compete for paying a restaurant visit bill. Some usual events occur as me going to have lunch or dinner with some friends. Maybe 4 people total. Say we all order about 15 bucks worth of stuff. Usually, it's the person who strongly suggested the go eat at so & so place to pay. But, when someone you know across the table gets up and shoves your money away with theirs, it's rather shocking. "WTF are you doing?" You begin to wonder, (we had a deal).

To some of you, this may seem very awkward for "nicest thing," but we work on a terms of secretly reimbursing that individual who paid. It's sort of a secret system of recognition. "He's always volunteering, he calculated the tip first and went to totaling the amount before we all did, he knows I just got birthday money and wants me to spend it on something more materialistic, etc, etc, etc." That's sort of what I get/got with having 3 best friends.

But when someone goes out of their way to take upon a serious task off your shoulders, that's a nice thing.

Jam it back in, in the dark.
