Tips

What you say is not particularly important(as long as it's not completely idiotic), but whatever you say, try to keep your conversation positive. Don't be negative, arrogant, or pushy; just be friendly.

When you first start talking with someone, don't aim to flirt. Just aim to have a conversation. This takes a lot of pressure off both of you.

Do not pursue anyone if they do not reciprocate. Walk away if the person doesn't seem interested. Don't presume they're playing "hard to get" because they might interpret any pushiness in a negative light.

Compliments can go a long way. It's a great idea to compliment the person during your conversation, but don't try to pass off a compliment that you don't really mean, and be careful about compliments that might be embarrassing or offensive (compliments about a woman's figure, for example).

If you don't feel comfortable asking for their number, try giving them your number. If they are truly interested in you they will give you a call. You could also pass them your email address that way the conversation could continue without any pressure.
