(Ladies, how many times have you felt a burning rage when walking down the street and hearing some stranger tell you under his breath as he passed you by that you would be a lot prettier if you just smiled?)
Oh the horrors! How dare some evil stranger say something to you that was most likely meant to brighten your day. If he had said "you're not as ugly when you smile", I concede your point.
At least he didn't follow up by calling you a conceited bitch.
