Don't worry about it, the whole 'never sign for anything' movement is overblown.Mailman comes to the door and asks me to sign for something, I have no fucking idea what I'm signing for, just the mailman told me I had to sign. Could be a registered letter from my bank, maybe my wife bought something online, or maybe Aunt Thelma wants to make sure I get her pictures of that Hawaiian vacation she always dreamed of taking.What would look suspicious is saying - no, I'm not signing for anything! That's not mine! Go away!Fuck, it could even be that strange kid you went to elementary school with mailing you a bag of bol weevil larvae. You have no control, no responsibility, and take no illegal action signing for anything, even if the contents are later shown to be illegal.And writing return to sender and waiting two days to open it isn't either necessary, or very fucking likely to happen either. If they are doing a controlled delivery, which they only do for serious large amounts, they hit that door seconds after it is delivered, not days. And by very fucking likely not to happen, I mean that when I get a dreamfully awaited piece of mail, that fucker is opened and being eyeballed, sniffed and examined before I hit the top of the stairs. No fucking what that's going to sit on my coffee table for 2 days first.So relax, it's not a big deal, and in the future make sure you're aware of the exact shipping methods the vendor uses before you order, so you don't have to go through this all again.
