write ,saying first that you hope all is well with him and his people. Then describe what has happened to your father, try not to make it too long. Then finish by saying “I know that my father would benefit from your help as an old friend, and hope you are able to meet this difficulty with him.”
I hope all goes well. You clearly are a caring son. Well done!
The two meanings for find would be
1. To unexpectedly realize something.
2. To unexpectedly realize the existence of something.
Example of definition 1: I walked inside to find a dog waiting in my room. (Realized the dog was a dog in the room.)
Example of definition 2: I never thought I would find aspartame in diet drinks. (Realized the existence of something, in this case aspartame)
I know it isn't much of a difference, but I'd say the homonym for find would be definition 2.
