Doesn't it suck when you're a nervous wreck, but it never quite dawns on you why? I don't think I'd have half my issues if I actually recognized what's bothering me right away.
Starting this week, my oldest son is going to be in charge of his little brother for a couple of hours each day. If I had real doubts about the situation it wouldn't happen, but I keep worrying that something's going to go wrong. After the first day, everything will be fine.
Unless my car explodes or something...
So, in answer to the babbling in my head...
He won't forget to pick him up.
He won't forget his key.
He will not break said key in the lock.
He will not forget his phone.
