Ah. I didn't see about how large the usage actually was. That's a lot. No doubt. About the only thing I can think of that might do that is the DirecTV, but you had that disconnected at that point. I wonder if maybe a device is getting into some kind of perpetual download loop. I don't really know. I'm not as technical when it comes to that sort of stuff as some of the people on here are. I truly hope someone can figure it out. That's a tremendous amount of data.
Sorry about your folks. That must have been hard to have them gone so young. I try to help my folks whenever I can. They helped me when I was down on my luck in the early 2000s, so I try to repay that any way I can. My stepfather is actually only 12 years older than I am (I'm 44), but my mother is 70, so I try to do what I can to make their lives easier. I live right across the street from them, so that helps, too. LOL.
