Often, me and my siblings as well as the parents would all work on a project together. This normally was either cleaning or preparing something, and most times once we got to a certain point people would just stand around. 

I was quickly the one to do this in cases, as when I was younger I was taught to get out of the way when something is going on. I remember cleaning the boat with my sister, both of us putting stuff on the back of the boat while we were just trying to get it mostly cleaned up. 

I was already spiteful because the day before I had been cleaning the house, I assume, and my mom or step-dad had told me that I wasn't doing enough, and that I was making my sister do all the work. They always caught me at the wrong times and it made me mad, I was obviously working it's just I always got done before she did and didn't want to interfere.

We had brought the vacuum up and started vacuuming the inside of the boat, and once we were done I was at the bottom but didn't want to interfere as my sister was getting out of the boat with the vacuum in hand. 

Of course at this perfect timing, my step-dad comes around the corner and gets mad at me for not helping my sister with the vacuum. I start insisting I was just getting out of the way but he got mad. My sister even started insisting she could do it alone, and he finally laid off. I was still pissed, but at least it didn't turn into me feeling guilty.
