Love to talk, that is the first rule about impressing a Gemini. Be knowledgeable about that you talk about too because Gemini are intelligent and have lots of knowledge about many things. If you are an expert on a certain topic, teach them about it, you will impress them because this know-it-all sign is does not usually know fine details about a lot of things, they are too busy to bother to learn. Speak your mind, engage them in a friendly debate but never be too conservative, they find this dull. Be honest and loyal to a Gemini, once they have had their trust broken they usually will never get it back again. Gemini are easy to date, they will do any activity anywhere. Just have fun, like you would with a friends because that's what Gemini are, a great friend.
