Things I assume when interacting with any woman:

You will approach me as an equal
We will greet each other
You will maintain behavior appropriate to the social mores by which we both behave
If I am with a child, you will be kind to the child
If I am with a partner, you will be polite to the partner
You will expect the same of me
The interaction will be of a length and depth that we both find acceptable
We will close amicably
