Glad to see I'm not the only one that happens to. Packages, certified mail, it doesn't matter, she ain't getting her fat ass out of that seat for anything. I've called and complained multiple times and it still happens. I watched her sit there and fill out one of those "sorry we missed you" cards and then drive off. I chased her up the road one day after she did that and she said,"Oh, sorry, it didn't look like anybody was home." Yeah, with 2 cars in the driveway and lights on inside that are clearly visible from the road I would think the same thing.
I just have stuff delivered to my work 90% of the time now.
