Habits

It's funny, the little things you get used to , and don't even realize it. I had a hat sitting on top of my TV, a funny, floppy paper one that I made myself. I'm quite proud of it, and I quite like it sitting there. But the sun was getting in my eyes when I was out in it today, so I came and got my hat to ward it off. And then my TV looked weirdly empty. Strange.
It's the same with my library card. I had the same one since I was a little kid, and I'd memorized the number. But my old card cracked, so I had to get a new one, and it has a different number, and it really threw me off.
It's the same when I get a new notebook, or I move around a piece of furniture in my house, or reorganize the dish cupboard to throw off my family, and I end up throwing myself off.
I guess it's the same with habits. I tap the ledge in my stairwell on the way down it every time I come down. If I slip and go rolling down the stairs, which happens upon occasion, I have to get up and walk back up the stairs and tap the ledge. It's just one of those things.
I wonder if that transfers to the way you act. Like, if you're always a little bit sarcastically evil, are you always truly like that? Is it just a way to cover what you're actually thinking?? A way to make people laugh? Maybe give yourself some inside-my-own-head time when you're in public. And can you stop it? Can you break yourself of that habit?
