Nonsense. You should always keep your hair the way you want it to be kept. If it's for work-related purposes, there are always ways to get around it. If it's because of something someone said, well, don't let others speak out against things like that.

I do enjoy wine. That would be lovely, thank you for the offer. I'm not particularly knowledgable about most wines, other than what pairs well with desserts, so bring whatever you feel is suitable.
