Friends, specifically Femme friends.
Most of my Femme friends are married or partenered but I have a couple of single Femme friends. Recently, I have enjoyed face to face time with a single Femme and I like that a lot.
It reminds me to display my manners. Get to the event early so that she does not arrive alone. Open doors, walk behind her, compromise on things like food, be polite, be pleasant, walk her to her car, and most of all enjoy her company and tell her that.
I get a little lazy with my manners around men and couples so this is new and fun.
