Guys will shave off beards or mustaches and people cant figure out whats different about them. Or get new glasses. A woman i worked with had a jay leno jaw and was out for six weeks having surgery on it to reset it - i thought she got a new haircut. Really people have TERRIBLE memories! And its not politically correct to comment on others appearance, so people might not say anything! Be prepared for any eventuality. I looooove makeovers
