The perfect invitation is usually the simple one. You have enjoyed a conversation, you think the interest may be mutual, and you would like to see her again. No elaborate scheme required, Montgomery assures you.
Be clear without making it heavy
Try something like, 'I've enjoyed talking with you. Would you fancy a coffee this weekend?' That gives a real invitation and a straightforward way to answer. You do not need to deliver a five-minute speech first.
Treat the answer with respect
A yes is a chance to agree a plan. A maybe may simply mean uncertain; do not interrogate it. A no is an answer, not the beginning of a negotiation. The way you respond matters just as much as the way you asked.

METHOD✶
Make it work in real life
Practise saying one uncomplicated invitation aloud. Keep it in your own words, with a specific low-pressure plan.
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.
