I found myself cornered by my owners anger toward me. That jerk got angry at me when I did what he set me to do. He was angry at me for "going off" at the time I was predetermined to go off. He had asked me to go off at a certain time and then hit me in anger when I went off.
I was durable though. I know I serve a great purpose in my owner's life. I assure his presence in the right places at the right time, which really makes all the frustration and anger worth it.
