Elevator Etiquette

I could take the title of this post in a whole other direction, and maybe I'll come back to this...but for this particular entry...

I was riding up in the elevator today on my way into work. Another guy also got in, just having finished working out in our building's fitness center. I noticed his collar was slightly up in the back exposing his tie. Normally, my first instinct is to not bother getting involved with something like this - why should I care, I don't know him. Then I thought, why not let the poor guy know (or maybe he's not anal like me and could care less). So I broke out of my public stranger shell and said "Your collar is sticking up slightly in the back". He immediately fixed it and made a funny comment about that not being the only thing wrong with him, thanked me, then we got to his floor and he departed. I felt better having positively contributed to someone's life. Why aren't more people as openly polite as I had just been. Maybe most are and I am the one needing a little fine tuning. Maybe next I will become a missionary and help refugees in Uganda. Or not.
