I just have to say some people need to grow up. Honestly why care what a stranger said to you? Really, I don't know you therefore I don't care if you are rude to me, that's your opinion and your business. If it was someone I know and care about like say my DH I would be upset but that's where communication comes in. So many people just need to grow up and let things go. They remind me of my 7 yr old SS who when he doesn't get his way or argues with someone screams and cries and throws a tantrum. Get over yourself!
And if someone disagrees and wants to argue go right ahead. Share your opinion because that's the point!
