So this past weekend I went out to lunch with a girl who had expressed that we should hang out sometime. This girl is a bit older than me, 26, and me, 20. We go to a decent restaurant, maybe $10 for a meal, so nothing crazy there. We were having a good time as far as I could tell, she kept on commenting on my body, saying I must work out a lot etc. She ordered drinks for herself and even told me she doesn't day drink often, so at this point, I am convinced that she's into me. The lunch ends and she tells me she is meeting a friend at a cafe nearby. I hug her as I leave and don't send her anything until the next day where I suggested that we watch game of thrones. She took about 4 hours to respond and said that she wants to watch the other seasons first. Is there any opportunity here, or is nexting her my best bet?

tl;dr, went to lunch with older girl, had a good time, she invites me to a party she's gonna have later this month, and admittedly drinks at an odd time for her preferences. Wait a day after meal and invite her over to watch a game of thrones. Takes a long time to respond and says that she wants to watch the others first. Where did I mess up if at all?
