Yeah, I know I'm a soppy old fool but this made me cry. As I get older, it never ceases to amaze me how short life really is. Yesterday I was the child, now even my oldest child isn't a child. Apart from death (and the dog), I've already ticked off everything in this list, and having witnessed my parents during dad's illness, I've touched on that from as close as you can before you touch it yourself.
Enjoy the little things, because it'll be over before you know it.
