Michael Sleep is the NPC younger brother of the big star Matthew Hamming, living in Bridgeport. He strongly dislikes his brother, maybe because he is jealous of his success, and is usually seen performing jobs like paparazzi, bouncer or mixologist, though when first loaded he is unemployed.
Like many relatives of Bridgeport Sims, he doesn't live anywhere in the neighborhood, unlike previous games where all family's living members were usually playable. He strongly resembles his brother, also having the same hair style but with brown hair instead. He has 4 points in gardening, 5 in writing and 6 in guitar skill. He is 4 days away from becoming an adult. He might be made playable by asking him to move in or by marrying him, but the odds are he won't marry as he has the Commitment Issues trait.
