Chinese Detective

A guy suspected that his wife was cheating on him, so he hired a Chinese detective... The cheapest one he could find.
This is his report:

Most honorable sir,
You leave house. I watch house. He come house. I watch. He and she leave house. I follow. He and she go hotel. I climb tree. I look window. He kiss she. She kiss he. He strip she. She strip he.. He play with she. She play with he. I play with me. I fall off tree. I no see.
No fee,
