One bite too many

My mom met this new guy,Derrick
He had a dog named sparky.
After he moved in with us a few months later he brought sparky to the
House. He was excited for awhile.
I started to play with him a little rough like eight grit sand paper.
He started to growl really and snap at. I kept doing it for a while and he got used to it
I went to him one day after school , messed with him for a minute
And then he growled really loud like a motor and then he jumped
of the couch like a spring as he went to go bite my nose i moved out of the way quick enough and then he jumped down and bite me on foot
I got some ice and it hasn't happened since that day
