Which sister should I talk to/ likes me?:

Sister A:
+Looks at me when I'm walking up the street to the bustop sometimes. I caught her looking at me and we stared for 3 seconds until I looked away nervously.
+Sits in front of me most of the time.
+Stared at me once when we saw eachother in the stairwell. Both sisters have gym with me. She stares at me sometimes from across the gym. She looks back up at me on the bleachers while shes at the bottom sitting with her friends. It seems like she only talks to 2 of those girls, the rest talk to her sister. We make a lot of eye contact, but we never smile and we always look away from each other. My friend added her on FB and she accepted, but I'm not doing that b.c I don't know her.
+Her friend looked at me today & laughed while they were in their circle. & she glanced at me while I walked down the hall and we were going opp. ways.

Sister B:
+Doesn't look at me as much, but it seemed like she did in gym today & then she talked to her sister for a long time. She glances at me when I'm making my way up to the bustop.

Why was her friend like that and is one of them hinting to me that one of them like me?
