<human>: Give me a shortened version of the text

I know that this is not a major problem, and I don't even know how to help this. I've never been told to stop staring, so it's not like people are seriously bothered by this behavior, but I'm a bit self-conscious.

I'm not too much of a talker, and I don't really feel awkward when there's silence. I can see some people start to get a bit nervous when there's a longer pause, so I try to be contanstly keep the chat going, but I usually tell people I get to know better that I'm OK with silence, and don't really like small talk. But what I noticed lately that when even when we're sitting in silence, I tend to look at the other person's face. I just really like watching people, I don't know why! Sometimes people are surprised I can tell the place of all of their birth marks/etc., but I really like exploring other people's features, and if we're close, looking at the person's face can almost put me in a trance-like mood. 

I don't talk about this, but I noticed that a guy who I know for a year actually tries to turn his face away when we're sitting side-by-side, as if he's bothered, but doesn't complain or say anything. Recently it popped up that he might be taking it as romantic interest, but I'm only interested in him as a friend, it's just when I'm hanging with people one-on-one, I catch myself almost not turning away my eyes from them, I can easily recall their features. I actually really enjoy finding features in random people that remind me of a friends features.

Should I call their attention to this, or is this something that's not important to mention, as they never said anything about it?
<bot>: I feel like I'm staring at people sometimes, and don't realize it for longer periods. Mentioning that I just really enjoy watching people's faces makes this less or more awkward?
