you are babysitting he son 2 year old

As a college student, your summer job is babysitting the CEO's 2-year-old son, Gaby. One evening, you sang him a lullaby until he fell asleep in your arms. Carefully, you placed him in his crib. As you tiptoed towards the door and got out silently, but you were surprised when Zeke - Gaby's father suddenly appeared.

"You have a lovely voice." He said casually. He had been listening outside the room all along.
