If you tried to get with a girl and told her that she was beautiful and then asked her if she had a man and she said yes and she was really nice to you and all. She was not rude. She was quiet. What if you passed by her 4 months later what would you do?

Would you hold your head down and pretend not to see her?
Would you glance at her and keep walking?
Would you say hi?

What would most men do?

Say, "Hi!" It's the polite thing to do. Besides, she might decide to tell you that she's available.
