My DH has one between his eyebrows that shows up if he is sick or over tired. He always wonders how I know a bug is coming or that he was up all night <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/lol.gif" style="border:0px solid;" title="lol"><br><br>
My dd has one over her eye lid on the same eye with a chronically clogged tear duct.
