I am a highly functioning autistic, and I do sing or talk to myself at times when I'm in a public place. From page 1:
I typically can control these kinds of impulses (or tics, if you will), but I have to be constantly aware of myself and on guard in order to stop them.
This is timely because the past few weeks have been stressful for me because of issues going on in my work life. DH mentioned to me last Thursday that I was "doing funny things" more often such as blurting out nonsensical words for no reason. His personal favorite was when we were getting into the car earlier that week and I opened the door, looked at the hood of the car and said, "Meesheewa eesheee" and then got in the car just as if nothing had happened and we both went to work. I don't remember doing that, but I have no reason to doubt my DH. It sounds like something I'd do.
He thought maybe I wanted the car washed so he got the car washed.
I've learned to live with it, as has my DH. I sometimes pace the kitchen or hallways for no reason. I'm not cooking or doing housework, I'm just pacing. If/when it bothers him, he comes and gets me and we go do something together like shopping, a movie or playing cards. I also stack and re-stack the linens, the paper products or "face" the canned goods. Repetitious action soothes me.
But DH finally said something when he came into the kitchen last Thursday and caught me rocking. I was sitting on the stool waiting for the water to come to a boil for the spaghetti and had my arms crossed over my chest, staring off into space and just rocking. It was a totally unconcious way of self-soothing. I felt fine, was probably dealing with the work stress in my own way, but I probably looked demented to anyone walking in that didn't know me. I think he finally had to speak up because he was becoming a little concerned.
Since then I've redoubled my efforts to appear "normal" and have been working on stress-reducing techniques to deal with the work issues. In addition to that, I increased my efforts to monitor my behavior, try to restrain myself from blurting out nonsense words (a tic that I've had difficulty overcoming since childhood), and employ distraction techniques such as focusing on favorite candle scents and background music.
This is what
I do. I can't say that all autistics do this but this is what works for me. Because I know what I do, it's easy for me to observe someone else behaving in a manner that may seem unsocial or inappropriate to the general population and give that person the benefit of the doubt.
The fact that the man singing the "inapproprate" lyrics turned away from the father and his daughters and started singing to himself leads me to believe that he'd dismissed them from his immediate attention and had gone back to whatever was going on in his head. When the man with the daughters behind him made a remark about his singing ("Dude!"), he likely assumed that he was encroaching on that man's personal space with his singing and apologized.
I could be wrong. I wasn't there. But I can easily see how this could have been me in this same situation and how someone could think I was unbalanced or predatory based on a 30-second observance. Fortunately, I'm a woman and don't really have to deal with the stereotypical issues that are foisted onto men. In fact, if I dyed my hair blonde I could probably get away with
all my autistic tics in public and never have to worry about what other people assumed of me.
