<human>: My stepmother, who was extremely verbally abusive to my older sister and I in the past, who I've always had issues with (too much to explain for this post), was sitting with me in her living room one day, and told me about her hidden stash of honey wheat pretzels.  She let me have a few, then stopped me after having a small handful, saying to save her some.  

I didn't plan on eating more, but the sheer fact that she felt that she *needed* to tell me to stop eating angered me.  This made me furious, due to past incidents like this, and due to the hypocritical nature of things (she would have gone ballistic if I had done the same to her). She continued shoveling handful after handful of pretzels into her mouth.
 
While we were sitting on the sofa with her bag of pretzels, the neighbor comes over to talk to my stepmother.  My stepmother goes outside to speak to the neighbor, leaving the bag on the sofa.  I got up to use the bathroom; however, as I got up, the bag caught onto my jean shorts and spilled onto the floor, where the dog usually slept.  In the heat of the moment, I took this opportunity to consciously and righteously spread the pretzels around on the dirty floor with my feet.  I put them back in the bag quickly, and acted like nothing happened.  I cackled in a sinister way at the evil deed I had just committed.  She comes back in, and continues eating them like nothing happened.

Give me the gist of the text in a nutshell
<bot>: Stepmom treats sister and I like complete shit for years.  Accidentally spilled stepmom's favorite pretzels on floor, then purposely rubbed my feet all over them, and put them back in the bag.
