Random Thoughts in the Library

So today I was just sitting in the library doing my usual thing, you know, studying for that boring econ class. And it's quiet here but still feels like everyone is watching me or something. Suddenly this weird thought popped into my head about how much I hate onions because they always make me cry when I chop them. Not sure why I started thinking about that, maybe someone was making a sandwich and the smell got to me somehow. Anyway, after that I remembered last week when I accidentally hit 'send' on an email meant for class discussion but it went out as a personal message to my professor. She seemed nice enough but still...kind of awkward, right? Now every time I see her in the library or during office hours, I get this feeling like she's going to remind me about that mistake, even though it was such a small thing really. Onions and email mishaps, what kind of day is today anyway?
