You smile, say hi, and talk to her casually for 1-2 weeks. Get to know her a little, ask questions about her, and tell a little but do not brag about yourself. Make her laugh by teasing her. Then, if you feel a vibe, ask if she has plans for the weekend and that you wanted to do this or that. If she has none, then ask her if she wants to come with you to whatever you wanted to do. Good luck.
