My House is Wack

So, I'm not sure what to say really. It kinda caught me off guard that my dad would come in cussing and spitting. It's really not like him at all. He said I needed to straighten up my attitude and pretty much told me and my sister that we were lazy leeches. It just seems to me that my sister and I were a bit singled out in this case... However despite my distaste for such a vulgar display I did what I was asked. My new rebellion is talking only when I want to and otherwise being the ideal, quiet, child.
