How Do I Handle My Boss Without Insulting Him?

Greetings to you ma'am. May GOD richly reward you abundantly for the good work you are doing in relationships and marriages. This issue has been eating deep inside me going to three years now.
Am 27 years old working with my MD who is in his mid forties. I must tell you that this man really took me as his daughter and I also run errands for him like a father.
