Wow. I don't think I've ever seen friendship analyzed that way before. I could probably learn a lesson from it. For me, friends are simply the people I know, care for, and willingly go out of your way to help. They certainly do come and go, tho most times I find it hard to strike up a convo with them after a long separation. But touch certainly seems to count for a lot with me and those who allow it in return.

Thank-you for being my friend, and allowing me to try to be yours. :-)
