Dads

How do dads always know what's wrong? How does my dad diagnose my perfectly, although of course I brush it off and tell him he's wrong? How can he take one look and say... hey my girl, you're sad.. when it's true? My dad is not a therapist. He's a dad and a good one. But what do I tell him? A pack of lies. Because I cannot come out with the honest truth, I want to enjoy him for several more years, and it's best that he thinks that his daughter being sad is a possibility rather then a definite one. But how does he know? I don't know. Perhaps it's because dads just know. Mine does.
