I sent my father a birthday card with a little money (I know, dumb) out in the mail on Thursday night. I put it in the post box right next to the post office in town and I made sure all my mail fell to the bottom and wasn't hanging out near the mail slot entrance. It gets picked up early at 5-6am and should have arrived at my Dad's house by Friday or Saturday at the latest. It's now Wednesday and he said he hasn't gotten it yet. I am concerned that the "woman" he lives with might have had a hand in why it's missing. (I would never say that to him though, it would just upset him.) My other thought is it might be lost in the mail. I figured if the postage had fallen off or they couldn't read the address on the envelope they would have just sent it back to my post box by now. Anyone know what I should do? I have never had a problem sending mail before, ever. I know it can happen, I just haven't heard of anyone I know having lost mail before. Any advice?
