best compliment

Perhaps a compliment from an adult child is the best kind. Why isn't there a word for "adult child?" It sounds so funny to call one's offspring a child, when they could be any age from 20 to 80. Mine are in their 20s.

I talked to my son today. He told me about a troubled friend. This son is sensitive, compassionate, and kind. Well, they both are. Anyway, this son has many troubled friends, and tries to help them.

I said to him, "You are so kind."

He said, "I learned that from you and Dad."
