Last time I was around her I had a cold and a stupid eye infection for some stupid reason. So I was like a pitiful little teary-eyed ball of mucus last time she saw me. Think she even wants to see me again after such a grotesque display?
Its not what you look like at the moment but how you presented your self. If you and her had fun last time just explain not in detale next time that you were sick and had an infection. Don't go into the "teary-eyed ball of mucus" deal.
