Americans are nice people

I forgot my wallet yesterday so I had to go up to some guy I see on the train from time to time and say "Hey mister, can I barrow 4 bucks?". With just about no expectation that he would see his money again (he will) he gave me the money. I had to print something out in the University library but didn't have my card and it was really important so I went up to a computer bank of strangers, held up my arms and said "people! I really need the money to print this". Instantly some guy in the front row who I have never seen before and never will again says "I got this" and handed me the money. A friend paid for lunch and another friend paid for the bus fare. I'm glad I was born in such a prosperous, generous place.
