Why are these guys staring at me?

I'm wondering if a guy likes me. I've been noticing for some time that he and his friends are looking at me a lot! Like on the bus, but also when I'm waiting for my bus. Even if they get off the bus they are staring through the window at me.

But the hardest part is that I don't even know which guy likes me (if he likes me) because all of his friends are staring too...

When I catch him or his friends staring he turns away quickly. They've been staring at me like this for at least 6 months.

I've also seen them staring at me when I'm talking to another guy. And I could've sworn that one of them took a picture because he was holding his phone in a strange way. But at that time his friends were not near, he was all alone.

What do you think?
