A friend gave me some work.
Originally I handled it, and then I handed the file to an assistant.
I gave feedback and guidance to my assistant. I thought it should be fine.
Then I discovered that it was not fine. The client was unhappy.
Lesson learned. Be personally involved in matters even if there is an assistant.
Personal touch matters.
In my friend's eyes, I shouldn't have taken the case if I wasn't going to handle it personally.
It's easier to remain friends if we don't take their case.
