People want you to be there for them ... But God forbid if you ask the same in return?

People get mad at you for expressing an opposing opinion but if they do the same it MUST be acceptable?

People think they can cuss at you, yell at you, or call you names ... but if you do the same, you are the spawn of evil?

I don't understand - what is with all the freaking double standards? I realize it's not everyone - but it's enough to make it a problem!
