where someone is on your mind, or they pop into your mind a lot, and things remind you of them. You may or may not like them
You may or may not be close to know them, or know them well
I feel this, with both guys and girls. From time to time my mind would "focus" on someone, and they pop up in my thoughts a lot. I would think of things in terms of them, or how it relates to them. They're just at the back of my mind. It varies from idle thought to almost obsessive.
It could be someone I've just met, or someone I think is interesting. But sometimes it's someone who I can barely relate to and who I don't particularly like. It's definitely not a crush in disguise.
I wonder to what extent it's related to sexuality. I don't think there's a conclusive answer so I'm not asking that. I just wanted to hear your thoughts about this kind of feeling. And whether anyone can relate.
