any ideas?

sometimes, and especially if you are the kind of person i am, you meet, observe or come across people who are very like you in very many ways. different ways, and many ways. but things don't really go any further (don't read too far into'further'). you know that if you were both 16 and had crossed paths with each other, you'd totally hit it off and become best friends. but now that you're older, more set in ways, in friends, and less inclined to take initiative to approach people and say "hey, will you be my friend?", you just smile from a distance and move on.

is there anything else you can do?
