SFW

A lady architect that we work with alot called a few minutes ago and wanted to know if I could tell her what "SFW" means. Apparently it was written on some old drawings she was looking at and she did not know what it was. All I could think of was "Short Fat Woman", but I didn't tell her that since she is short fat woman. I had to tell her I did not know. It's really hard to be a nice person sometimes. LOL
