Here's a question (OK, a bunch of questions) for you...
How do you express affection? Do you do it often with a few folks or with many people? Why? Do you not do it much at all? Why not?
I ask these questions because I've been thinking about the subject myself and am realizing how important it is to me. However, I don't think everyone can (or even should) do it the same as I do.
I only show affection to a few people, but for those few I try to do it on a regular basis (even if I'm irritated with them). I do it sometimes with words, but more often with body language (hugs, a touch on the arm, etc.) and actions (helping them with a task, for example).
Why I do it is more complicated. I do it because I know I need it and want to do unto others as I would have done unto me. I need it, so I give it, because it makes me happy and I assume it will make those I care about happy. I put that word, "need," in italics because it expresses how important I realize it is to me. Disturbingly important, actually. As someone who subscribes to some Zen philosophies about attachment and desire, having this sort of anxious grip is worrisome. It is a vulnerability. On the other hand, recognizing and embracing one's vulnerabilities is one of the lessons of being human, isn't it?
How would you answer the questions above? There are no right or wrong answers.
