I know someone in my class from last semester, but haven't seen her at all recently. We are acquaintances, not really friends.
I basically said hi to her on facebook, and she said things are going great, and how I am doing.
What should I say in return? Saying "things are great etc etc" will obviously end the conversation right there, yet I can't just ask her out or something.
Advice? besides try to strike up a conversation on fb, then meeting her.
