Oh, best wishes to them, but I know what you're feeling. Cry away! I know you know it's all right to feel the loss and the passing of time, because the news is happy and you feel the joy as well.

But, oh, that mid-life thing is killer. Once I cried while driving from Boulder to home, a 45 minute trip, which was hard because I was actually driving. But I felt the loss of my youth so fiercely. (I lived in Boulder when I first moved to Colorado, and to see it still full of young students hit me hard.)
