Socially Awkward...

So, apparently, Matt says I have this annoying habit of mouthing the words people are saying when they are talking to me. Or, occasionally, mimicking their facial expressions. Who knew! How long have I been doing this?! I had no idea! And I am just now finding out about it? How embarrassing and socially awkward!!! Has anyone else noticed this about me and just not said anything? If so, you are a horrible, horrible friend!
