why is it that there are ppl you don't start getting close to until it's time to go and then you realize that you liked them a whole lot more than you thought???

it's crazy but w/ these select ppl, it drives me nuts when i don't talk to them and when i see them online or when they start talking to me, it makes my day. i wish i could spend one day w/ them just to remember how much i fun i had....and see if the same things are still there.....anyone care to work for me so i can go see these "ppl"???
