Just be yourself.

Be respectful. Just because of the site you are on doesn't mean you can say anything to her.

Excellent question. Well, from my experience talking to women older than you as a younger guy takes a lot more finese. And the bigger the age gap between you, makes it a lot more difficult. Don't think that just because you are younger, that it will give you a massive edge. Most of them have already been through rough divorces, have kids and are not impressed by stupid bullshit lines or faux confidence. They might be flattered, and even flirt back a little, but they sometimes won't take you seriously especially if they have grown sons your age. Don't act like a fuck boy, don't come on strong and try to avoid talking about the age difference. You don't need to read the New Yorker, just be able to keep up with genuine intelligent conversation. Keep it casual and don't come into a conversation with the expectation of getting ass. Of course, exceptions to the rule and some are just looking for D. The classy and better mature women are worth the effort. I hope this helps in anyway
