I used to blush loads when I was younger you know in front of the class, I kind of grew out of that. Now I have the same problem I start blushing at the most stupid things,and its a self perpetuating thing, once you start doing it , you think about it next time you in a similar occasion become concious of the possibility of it happening and WHAM before you know it are as red as rudolfs nose. Dam its so annoying, and people really dont understand why you are blushing, or put it down to something its not.
