Neither snow, nor rain, nor heat, nor...

Have you ever missed an important phone call? Don't you hate it when that happens? Especially when it's from your son who's in boot camp, and has had only two opportunities to call you in seven weeks, and he got the answering machine both times, and he tried your cell phone but you'd taken it out of your pocket for two minutes to clean your lap of the salad dressing that you'd spilled, and he tried his dad's cell phone which was ignored because it looked like a wrong number, and he tried a friend down the street who was recovering from surgery and was sleeping very soundly.....
Makes you start to wonder if you were supposed to talk to him, after all.
Then, two days later, you receive a letter in the mail, and it's one of the best letters you've ever read. Don't you just love it when that happens?
