If it is about social interaction, I have some success with women (it doesn't yield a relationship immediately, but it makes me more comfortable with NT women. There aren't AS women that I tried out the following with):
- often smile to them. Some women like to be smiled at, but there will also be women that won't smile back, because they are in thought, or want to give a signal that they are not interested in you, or in a chat;
- making jokes, flirt in a non-sexual way. My jokes are often word games and often enough puns. And I like to take things literally with a humoristic effect. Girls and women often smile in that case. That way I can see whether there is a social match;
- social talk. Comment the weather: "It is very hot, isn't it?" Sometimes: "Haven't you melted away because of the heat?" especially if there isn't a ventilator or an airco and she does suffer from the heat. This is a joke, but with some empathy in it;
- despite of the post above, ask the girls and women where they work. I consider this as an open question. The answer the girl or woman gives can lead to way more questions, and then you have a vivid conversation;
- be careful about talking about your own interest. The girl may ask questions about your interest afterwards, but it is possible it is a social turn off, if you talk about your interest, your hobbies, and the girl can do nothing with it, simply because she doesn't know a thing of it. What on earth can she ask?
