I found out today (in a text message from my mother, randomly. I think it was the first time she's used that feature!) that a family friend died yesterday of a heart attack. Although I wasn't that close to this man, I always looked forward to seeing him when I go home. He's always quick to check my left hand for a ring! I called my mom to find out details, and she said that she'd been thinking about him last week and had intended to write him a letter and to invite him to a Christmas party. She never got around to it. Earlier in the week another friend of my parents passed away of cancer. She'd been in the hospital for a few days, and my mom had wanted to visit her one evening and didn't go. Two days later she died.
Just another example of the all the unknowns that are manifest in this life. Don't have any regrets - go for what you want, let your friends and family know how much they mean to you, and if you come across a cute guy/girl, don't waste any time getting to know them. Nothing to lose and everything to gain!
