How many times have mentally slapped yourself for thinking something absolutely stupid and ridiculous?

I did. Today. Twice.
My possible-crush asked for some lip-balm and I gave it to him. Duh. But then my mind went ahead and thought- You know, this is almost kissing. In a way. Oooh. Wow, gurl, yay.
Annnnnnnnd then I slapped myself. Hard on the face. Mentally. Don't want to look more of an idiot than usual. But the plus side is that he thinks I'm really smart. I think I'll shut up now.
