Tip for military moms

Don't ever tell your son to call you at 5:00. Of course you were thinking 5 P.M. Of course he heard 0500. Of course he did what you told him to do. And of course it was a Sunday morning and the phone woke up the baby. Just adopt the 24-hour clock; it'll make everyone's life so much easier. And while you're at it, use military letters, too, oscar kilo?
