This is not normal behavior, turns out. It is, however, an odd habit that I developed as part of a sort of grazing behavior that has persisted since I was a kid. When I was still fairly small, my family stopped eating meals together. By the time I was eleven or so, they'd stopped preparing food for each other all together, save for holidays. After that, my mom went to the grocery store and my dad went to the bulk store to buy food. Easily three quarters of our food inventory at any time was dry goods or frozen stuff, though we usually had bread, eggs and some kind of cheese hanging around. Maybe some fruit, too.
It's not like we went hungry, just that until I could cook more than just scrambled eggs, I lived on Bagel Bites and chips and salsa. When we ran out of those things, I'd move on to other, possibly weirder stuff. I ate taco shells, sugar cones, large amounts of oyster crackers with spoons of peanut butter. Someone would eventually go to the grocery store, and the process repeated.
Nowadays, I eat at the office more than I do at home. I don't have a lot of snacks here, so I tend to eat the same three or four things over and over. It's not even a matter of being picky, as I enjoy foods from Thai to pizza to Ethiopian, but I simply don't mind eating the same veggie/protein/carbs combo a few times each week. I sometimes wonder if that's another holdover from the limited menu of my past. Again, it seems normal enough to me, but the other human who lives here disagrees.
Don't misunderstand, I'm not equating my weird eating habits with some severe form of child abuse, I just learned something new. Despite their deliciousness, sugar cones are only intended as holders for ice cream...we'll see.
