When out to dinner, order for your lady friend, then yourself
This one is a little controversial these days. Back in the when, it was customary for a gentleman to find out what his lady wanted to eat, then he would tell the waiter. “The lady will have…” These days, some ladies feel weird about this. In my eyes, it is not something you do every time you go out, but dropping it in every now and then is a treat. Especially if you can pull it off without directly asking your lady friend what she wants. It shows that either A) you are listening to her thinking out loud or B) that you know her well enough to remember what she orders at a restaurant. Either one is Milhouse.
