No fee, Chen Lee

A man suspected his wife was seeing another man, so he hired the famous Chinese detective, Chen Lee, to watch and report any activities while he was gone. A few days later, he received this report:

Most honorable sir,

You leave house.
I watch house.
He come to house. I watch.
He and she leave house. I follow.
He and she go in hotel. I climb tree.
I look in window.
He kiss she. She kiss hi.
He strip she. She strip he.
He play with she. She play with he.
I play with me. I fall off tree.
I not see.

No fee, Chen Lee.
