I ordered two items for my husband for Christmas this year. The items came on separate days.
I can not see if anyone pulls into my driveway. FedEx delivered the packages, walked into my opened garage laid the boxes down and left. They did not knock or come to my front door. My husband found the packages and opened them to see what had been left.
So now my husband knows what he is getting for Christmas.
Even if they had left the packges at the front door there would have been a chance I would have found them before my husband. And even if my garage door was opened, no one should walk into it, that is like just walking into my house.
