So there's this guy that I work with.  He is unbelievably sweet and hilariously funny.  I fell for him... and now I don't know what to do.  He is six years older than me but my parents know about him and they don't seem like they object.  Sometimes he drives me home from work and other days he picks me up when he sees me walking. I love the way he smiles and the way we joke around with each other. His last name starts with the same letter that mine does so all the little kids at work think we are married. The best part, is that he goes along with it and makes it actually seem like its for real. Now...what on earth does all of this mean?? Is he flirting? and what do I do?

ps-sorry, just needed to get it off my chest
