Added: Just saw your SWH - didn't mean to offend. I was talking about the outdoor part being better than working inside. He certainly hopes to find a LIVE child - the kid is lost, surely not dead. No offense intended, R. - I didn't mean it the way you took it, and I'm sorry. I was agreeing with YOU about him needing to work. Going at night sounds like a good compromise.
Original:
R., it sounds like it's a way to get off of work without looking bad to his employer. He's an outdoorsman (likes to fish?) and this is outdoors, but for a worthy cause.
I agree with you, and most probably he does too, but he won't admit that, and he's mad that you bring up the truth, when he would rather not hear it. Only you know your husband - we really don't other than what you say about him, but from your description about him not being "humanitarian", I think that this is really about him wanting not to be at work.
I hope he listens to you and goes to work anyway, even if he grudgingly does it. And if you can actually go and help (do you have someone to watch the kids?), that would be wonderful.
Sorry!
Dawn
