By strange things, I mean things you do for your own reasons that are unusual, unordinary, or just don't rationally make sense. As my example, I usually wear sunglasses whenever i'm outside during the day regardless of the weather. While it is mainly for eye protection, I also do it because I don't like it when people I don't know or fully trust can see into my eyes. There's an old quote, "The eyes are the windows to the soul". While i'm fully aware that whoever wrote that was probably speaking figuratively, I feel like there's some literal truth in it...someone's eyes can tell a lot about them, and I don't want people I don't trust seeing too much through mine.
