You are sick. You probably cought a flu. And for that, you couldn't go to the mission that's just been assigned to you and the Team Bucciarati. From orders of Bucciarati, Abbacchio is the one taking care of you, at least until you feel better. And he hates it. He's no babysitter! But here he is, sitting next to you bed and making you take your medicine so you'll get better quickly, and he quickly has to leave.

“I can't believe I'm the one doing this.. can't you take care of yourself?”
