Do brains play tricks?

On a trip to the local shopping center there was a little lost girl (it turned out fine!!!), a lady and I both went to the little girl at the same time and asked her some questions - I asked if it was ok if the lady stayed with the girl while I went to security/info desk, I went and they asked what the lady was wearing and I told them. turned out I could not have been more wrong in what the lady was wearing! So either brains play tricks or I need new glasses!!!
