Don’t come on too strong, compliment something that she put on that day, not how she looks. Like her hair, or her outfit or something. Ask for her name, what she likes to do, etc. Ask some conversation starting questions to inquire about HER. Don’t share too much about yourself, and just when you guys are at the peak of talking, ask for her number or to take her out to eat sometime. Read her body language though and don’t proceed if she’s obviously uncomfortable. Be nice and respectful
