Why were his friends watching me?

Anon as I have friends on here.

I'm in my second year at university and I've been sleeping with a guy on and off since around January. We go over to each other's but I tend to prefer going to his. Last night I was out on a social with my society and I bumped into some of his friends (some of them he lives with). They are all nice to me and they always say hello whenever I bump into them, and last night was no different.

However, I was in the shisha garden last night and I remember looking up and seeing his friends looking at me. I thought I was being paranoid but whenever I looked up they were stood facing me and looking AT me :s-smilie:
