Weird Habits?

[Oneesan]

I just realised I eat sandwiches weird if they're cut diagonally in half, I always bite the corners off first before biting the middle.
:/

I do the same thing Have been ever since I can remember.
I also am obsessed with locks. When I leave my room or the house, I will lock/unlock the door 3 or 4 times before I go. We live in the middle of nowhere, but I still can't stop. Better safe than sorry.

I also bite my lip, don't even know that I am doing it until it starts to hurt
