Agree with your entire post, and yes, this was a whole pizza box of garlic bread!
The funniest part of the whole 2 hours was when she took 2 slices of pizza, and put them on a plate, so I was like, ok, 2 slices is fine. But no, she handed that plate to her daughter and she kept the rest of the pizza for herself!
Then she added in about half the garlic bread, and the brownie box was an entire box, and she just dug her fork into the brownie box, rendering it useless (or gross) for anyone else.
My mom had a food addiction. She'd buy a half gallon ice cream and eat it with a spoon. If she didn't finish in one sitting, she'd put it back in the freezer, which even as a kid, I thought was too gross to go into. Plus, we knew she'd come back wanting that later. She also ate 1 lb. bag of M & M's in one sitting, only giving us a small handful if we asked.
She (my mom) would be up all night most nights, as she was a night owl, and her tortilla chip crunching was so loud when I'd stay there (as an adult), I'd have to wear earplugs to sleep (not kidding). She'd go through an entire large bag around 2 am.
She died a year ago, with diabetes, heart disease, barely able to walk, and had a nasty, selfish demeanor. I'm 1000% convinced that her diet played an enormous role in all of this. So when I see the Bethany's of the world, inflicting their habits onto their kids, I shudder for those kids.
