Eyelid twitching!

This is hilarious. A friend mentioned last week that her eyelid kept twitching. I thought no more about this until a few days ago when mine did the same! Since then I have had a few short bursts of my right upper eyelid twitching, so out of curiousity, I looked this up in Google. I guess I should not have been surprised to see that it is everywhere! Popular causes seems to be stress and lack of sleep. I am not stressed and I get enough sleep, so I suspect mine is a 'sympathy twitch' for my friend! :-)
