One or two little sentences to folks like that...and I LOVE To use it.....goes something like this ---->

"I feel sorry for you, it must be really hard each day to have to get up and face the world with such a negative and ignorant attitude such as yours. Hope you have an awesome day!"

By the time they are done reading that, they have no idea what just hit them.....then you are gone and feeling oh so smug LOL I just love pissing those kind of people off I know...I'm really really really bad
