How to say face-to-face fortune telling

Today, a fortune teller asked me if I wanted to tell a fortune. I said, how old am I? He asked me to show him my hand. He really worked out my age. Please.

Don't believe his story. A person's age is similar to his appearance. 18 and 19, too. You 18. 19. If he doesn't tell the right time, he will give you a fictional age. If he is true, he will tell fortune. Why not plan yourself better? And (that's how he lives on the streets) is really nonsense.
