I haven't talked to her yet. I saw her many times in the hallway today and she always looked at me, not sure if I should make eye contact back or what. I think I will make a facebook, add a few friends and hope that she adds me.
You asked her if she wanted to grab coffee. Then you asked if the time worked. Then you asked if the place was okay. Then you asked if she'd prefer tea.
Four questions. Four chances for her to say no. Four signals that you're terrified of making a decision.
Plan it. Pick the place. Pick the time. Tell her where to meet you. She'll either show up or she won't.
Either way, you look like a man instead of a scared little boy.
