A Question About Ethics

I ask you a simple question, how hard is it to respect the work that some else does.  I understand possibly not agreeing with it, but to disrespect it seems a little over the top to me.  I have noticed now a days people seem to disrespect other people for no purpose other than to make themselves feel a little more important.

I was talking with some people yesterday at a networking event, and we were all agreeing on the presentation that I have given earlier.  There was mention of how a work day can take off on its own and leave your to do list in the dust.  Of the people in the room, I would say that most if not almost everyone to a person came up to me and stated that it was a very realistic picture of small business.  I thanked them and shook hands and of course we did the inevitable exchange of business cards.

However there was one lady that came up to me while I was with a group of people and stated "I never have those problems, you might want to think of just how successful your business is going to be when you have to make such an outrageous claim to sell your services".  At that point I didn't have to say much as many of the others around me took the torch up and help clear a path through her obviously meandering mind.  I never said a word to her, (yes this is the truth, although most of you who have known me long enough might not believe it) and I don't regret it because I realize she is just one person.  However that got me o thinking how many others could she have done this to, and why does she believe it is alright to disrespect me so publicly.

I don't really know, but ... is it an ethical question?
