Isnt it funny how even the smallest chance meeting can change a person, especially one in trouble, Its like you meet this person, you give as much thought to them as anyone else cause, well...thats what I usually do whether right or not. But they are changed by you some how, you are too I guess, but say they're more aware of this than you, and for years they remember you and think of you and maybe even gain strength from the thought of you.
And so you see, isnt it funny then how we think we are not important, in the grand scheme of things.
