Input: Text: this actually happened to me about 15 minutes ago. me and my family just finished watching the new star wars movie, which is fantastic if i do say so myself, and since there's 6 of us, we took two cars. my brother and step-brother took his car, and i rode with my dad, step-mom, and step sister. let me just start off by explaining that my step mom completely pampers my step sister, who is around 12ish. she gets whatever the fuck she wants, always. she is such a brat, even my dad's dad dislikes her. but since i want my dad to be happy, and my step-mom is pretty cool sometimes, i try to get along with her. now, it seems like no matter what argument is going on, she always picks her side of the family and defends it to the bitter end, even if she knows she is wrong. this often pisses off my dad, but lets get back to the story. so were all in the car, and my step sister notices i have some reese's pieces left over from the movie. "ohh, reeses! can i have some?!" to which i reply "sure". so here is my first mistake: i decide to give her some, i pour about 5 into my hand as she has her hand held out, put my hand over hers, which she obviously saw, then release the pieces, to which she retracts her hand in a type of horror like i had just committed some war crime in her presence. the pieces fall to the floor, and i am bewildered. i assume it was some sort of mistake, so before asking what happened, i proceed to pour more into my hand to give to her, and extend my arm to her. "i don't want those, give me the box." she demanded the box, and i was already trying to do a favor for her, since i could have just told her no, so i said "here i'm giving you some, you don't need the box." she replied with "i don't want them if you have touched them, i don't know where your hands have been." now folks, i don't know about you, but that seems like an insult to me. she asks me for a favor, then tells me i'm too dirty to give her said favor with my own hands? so then i refuse to give her more, at which point my dad overhears the arguing and asks whats going on. i explain the situation, he says to just pour her some out of the box. i say "so she gets some even though she was rude to me?" he thinks about it for a second, and says it was probably an accident (the hand retracting, causing the pieces to fall on the floor), and she explains it wasn't. he says to her that that is rude, and then my step mom suddenly chimes in in an absolutely livid voice "i disagree. she doesn't know where his hands have been, if she wanted some from the box that is not rude." to which i point out that she didn't ask for it out of the box, she demanded it. she said that its still not rude, at this point i am absolutely up in arms about this, because from all i've been taught, this is completely rude. i then proceed to  point out that we have all been eating out of the same buttery popcorn bucket for 2 hrs and 16 minutes. at this point, my dad chimes in and says to end it. i knew better than to think it was over, i could see her in the front seat, her anger practically boiling over, fogging up the car windows. after about a minute of dead silence,  she suddenly exclaimed "who bought the candy?!" to which nobody replied. she asked again, and my step-sister replied "daddy did!". "give it here." she said with her arm outstretched and palm open. i didn't move. at this point i was simply trying not to scream at her about how much of an enabler she was. "give it here!" she yelled. i didn't move a fucking muscle. my dad then outstretches his hand and says "give me the candy." i immediately react and hand it to him. my step-mom then held out her hand as if he was going to hand it to her, to which he just glares at her, opens the box, eats half the candy, then puts it on his side of the car, and keeps driving. now, my step mom is pissed at me, my step-sister brought this up to my brother and step brother, so now everybody knows, and my dad and step-mom are very upset at each other. now i'm sitting here typing this out wondering if what i did was right or wrong.
