I think a lot of it has to do with being on the same wavelength.
I've only had one relationship where SHE came into my world and took an interest figuring it out.
A lot of women seem to like the idea of me or they like how other people see me. But that doesn't mean they necessary take the time to ask the question of why.
I have a sort of personal motto, that seemingly none of my roommates share. If there is a guest in the house in the evening, I will feed them. At our house, everyone cooks for themselves, except for me, I cook for other people too, roomies, friends, neighbors, whoever. If you are here when it happens, you are free to have some.
One of my roommates has this pothead friend and she comes over all the time. Enough that I've cooked for her a handful of times and I've ordered pizzas for the house a handful of other times when she's been here. Apparently no one is consistently nice to her, because she thought I liked her and that I was being coy, so she asked me out. In a darker chapter of my life I might have said yes, but it made me realize that a little hospitality goes a long way.
When it comes to me, I usually act first and then talk about it later. If I love a woman, my creativity needs to be stifled and my actions require reining in, so that I don't come across as a Psycho. But not everyone is wired to make the message in a bottle in a treasure chest with a treasure map. Not everyone bakes cookies, for no occasion but to say that they care. Not everyone cuts work or plays hookie from school just to surprise the other person.
When I'm working my magic, everyone knows.
