Why do I need a disclaimer?

Through out my life both of my brothers have made friends that I never met. I would listen as they tell stories about these great people, or not so great people depending on the story. Well, if my brothers decide that this person is cool and worth having around in their life, I am then allowed to meet them. It always plays pretty much in the same way.
Me: "So I am meeting John Doe today. Will I like them?"
Brother (really this could be either one): "I think you will. I REALLY like them. I have told them so much about you and they wanted to meet you. "
Me: "Huh? They do realize that I am a demi God and that they will either worship me or be smoted right? "
Brother: "I told them you can be a bitch. But I really like them. "
(This is the point when the send me some pathetic plea they both say the same thing
Brother: "Shiela be nice."

Be nice?? It's not like I walk around eating baby fetuses and barbecuing puppy dogs. Why I ask you do I need a disclaimer? I feel like I should have a parental advisory label, and if Tipper had her way I would be forced to have it tattooed to my forehead, but that is a different subject. The truth is I always play nice. I let the little things slide and I smile. But one certain occasions my brother will put forth a lamb and I am but a lion. The will parade in front of me the stupidest person they could find. I think that maybe these people aren't actually there friends, but it is a set up and they are just taping it for a reality show to air years from now. It's title will be "Over protective sister gone wild" Everything you like about girls gone wild except the boobs aren't on her chest they are trying to talk to her.
I think it will catch on. Anyway I am left feeling guilty and evil because there is only so much infantile things I can take before I snap. And when I snap it is more like Chernobyl then just a rant. I quickly spring up on my soap box (I carry it in my pocket and never leave home without it because you never know when the self righteous mood will strike and I will need it) I twirl around three times like wonder woman then I will become Soap Box Girl. Now everyone else calls me "bitch" but I prefer my name for obvious reasons. When I transform I am not in control of my body, the enigma of being right has taken over. I will begin inhaling this poor person who will be on the verge of tears before I am done with them. I will look over at my brother who always has the same look, the one that says "fuck, I knew she was going to do this." Most of the time that is the end of their friendship because regardless if I was out of line if these outsiders try to say anything negative about me my bros got my back.
So you see I can't help it if I am an unelected super hero, but someone has to clean up the streets and put stupid people where they belong (the swamp to help with the inbreeding process) But in the end I am "nice" and I blame it all on my brothers for not doing a thorough background check before displaying these intelligence terrorist in front of me.
