CoD4 is an awesome game! Definitely worth Checking out. Though if you play a lot and have the time for it it can be beaten in a couple days if you want to rent it. Very realistic and entertaining. Great historical quotes in it as well.
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.
