I pretty much give up after a few questions and assume she's not interested. A few days ago, I was at a shuttle stop waiting to head back to my dorm. I saw a girl come and sit near me, so I asked, "Hey are you heading to [insert Hall name]? She said, "yeah". Now, before you say I asked a stupid question. There are 3 different destinations that shuttles take students to, so it wasn't obvious that she was going where I was going. I then asked, "how long have you been waiting? She replied, "A while", I then mentioned, "these shuttles take too long." Then I asked, "by chance did you just move there this semester?" Turns out she was there since last semester and I mentioned, "It's a wonder I haven't seen you until now." I asked her what year she's in and she said she was a fresher. Felt like an interview because she didn't ask anything back so I stopped.

Yesterday I was coming from the gym and I saw this girl pass by me who I had seen on my Hall a few times, so I asked, "Hey, did you move in on [insert Hall name] recently?" She said no. I then said, "I could've sworn I saw someone like you there." She replied with, "yeah I have friends there." "Cool...", I replied. "Are you from [insert country's name]?" She then said yeah and I said, "nice." and I stopped talking then and there and she just kept on walking.

So, I'd like to know: Do I give up too easily? Should I ask different questions/say different things? Am I doing everything right and these are just situations where girls just weren't interested?

P.S. That's all the approaching I did this week.
