Thanks @deanliu for sharing this. It really tugged at my heart. I left the SF bay area in 89. When facebook started gaining steam, I went on and found all my old friends. One friend, Dave, accepted my friend request, but never seemed to post or respond. He's too busy I thought. A couple months later another friend informed me Dave had passed away a year prior, and that his daughter was maintaining his Facebook account. (To Dave, I miss ya bro.) Thanks again.
