Dear Janis:
Blushing is a nervous reaction that triggers tiny blood vessels in your skin to widen. This allows
more blood to flow to your skin and creates that reddening effect that you seem to know all too
well. Blushing just happens to be your way of reacting to a particular situation. Someone else may
not visibly blush, but they may very noisily tap their fingers or clear their throat. Everybody is
different, but everybody gets embarrassed or nervous sometimes!
Signed,
Wendell
