When I was little I somehow got in the habit for a short time of making this squeaky noise in my throat. I don't think it was loud enough to hear because my mom never told me to stop it...but it was the first time I felt like, "what makes me do it and I really should stop."
I have been a nailbiter all my life and it embarrasses me more every year. Especially the last several years because I also have eczema on my hands and people somehow think it's ok to gasp and point and say, "what is wrong with your skin?"x-(
Lastly, I get some brief, weird satisfaction of "grooming" hubby like monkeys do. If he has something on him like a peeling sunburn, I am glad to take care of it...I don't want people to know I do it...but I am glad to be of service in private
