Do you think this means anything?

yesterday night i was at a sleepover with some of my mates and we were playing about and stuff then when we all went to go to bed i was the last girl awake with my best mates older brother and my friends boyfriend anyway i am laying on thge sofa with ym PJ's on and a a duvet over me and i was watching the two boys play football on the PS3 and i was dozzing off. Then i look over to the boys who are sitting on the other sofa nxt to mine and i caught my bet mates brother looking at me.Then he quickly turned back. ( i dunno if he thought i was asleep or something..) I was looking over at him a few times but it didn't notice because i just moved my eyes ( not my whole head) I caught him doing it a few times b4 we all went to sleep at 6am!B4 that happened the brothers mate took the place where i was and the brother kept telling him to get ou of my bed.During the night when i was awake with the guys the bf kept asking if i wanted to swap with him so i would be next to the brother as joke.
