Patchy is my ears

I sat in the living room reading a book. The sky was blue and Patchy laid on my lap. Suddenly Patchy jumped from me and went to the wall. His nose was touching the plug-in door chime with flashing light, used by deaf people to show that there is some one at the door. I did not notice the flashing light due to the strong sunshine shining into the living room. It was the postman with a parcel for me, for which I had to sign to acknowledge receipt. I am so glad that I have Patchy. He is my ears.
