Hope this helped.

My take:

"A witty comedian who fears showing his feelings must learn how to support an an old friend who is shattered by his daughter's cancer diagnosis."

I changed it from losing an old woman to losing a young woman, that is much more intense and difficult to process. Burying a child is perhaps the single most painful experience a parent can have.

thanks for all the feedback, really appreciate it:)!
