Well, M., I can tell you that I have been twirling my hair since a child--and now I'm almost 40!! In fact, I was just twirling my hair as I read your post. And I sometimes still get my hair tangled. I try to be conscious of that while at work, as I think it looks unprofessional, but sometimes, if I'm deep in thought, I don't even realize I'm doing it. My father has been after me for years to stop. I do my best to stop when I'm around him as I know it bothers him.
Most of the time, I'm not aware I'm doing it. By your post, it sounds like your daughter isn't aware either. It's a habbit that can be annoying at times. Maybe if one of my children starts doing it, I'll see how I don't like it and actually stop myself!
Even if her hair was cut short, I do not believe that will alleviate her twirling her hair. The only way is if her hair was shorter than what she could twirl.
I am eager to view others responses.
I wish you the best!
Happy anniversary!
Looks like we are very similar in anniversary and age - my husband and I have been married for eight years and I'll soon be 38!
Take care!
