Good flirting feels like a conversation with a little sparkle, not a performance from a bloke who memorised thirty-seven lines on the bus. Pay attention, be warm, and let the humour grow from what you are actually talking about.
Let the moment provide the joke
A shared mishap, a harmless opinion or a funny coincidence gives you something natural to play with. Avoid teasing about insecurities, appearance or anything someone has made clear they dislike. The best banter leaves both people smiling.
Read the response and adjust
If she laughs and adds to the joke, wonderful. If she gives a short reply or changes the subject, let it go. Being able to shift back to an ordinary, comfortable chat is a greater skill than delivering one more clever line.

METHOD✶
Make it work in real life
Try one light, situational observation instead of a rehearsed chat-up line. Then ask a proper question and see whether the exchange develops.
Everyone brings different experiences and expectations to dating. Pay attention to the person rather than relying on a single rule, and don't assume somebody else's interest, availability or intentions. A good outcome is clarity and a respectful conversation, even when romance does not follow.
THE GOLDEN
RULE.
Attraction isn't a switch you can flick in another person. Work on being somebody comfortable, engaging and respectful to spend time with — and give others the freedom to choose for themselves.
YOURS, MONTGOMERY.
