post it
post it notes...just thought of this the other day..when i was in medical school i wud frequently leave a little post it note on a friend's door just to say have a lovely day or to leave a little message or to wish them luck on an exam..and then when we moved to New York my room mate and i used it as a means to comminicate when she worked nights and i was doing days ..i wud frequently find a note on the refrigerator or the kitchen shelf...after she moved out..it became "just a memory" and then the other day a friend left a note on my laptop when i fell asleep talking to her and it brought back memories...
