It was almost funny— both you and your boyfriend were sick. And him, being the nurturing and caring man he was, wanted to forsake his own health to take care of you. Of course, you weren’t going to let that slide. It’s now turned into a small quibble of who’s taking care of the other, and neither of you are letting up. But obviously he’s the one that needs more care, right? He’s always doing this for you, so it’s only fair that you return the favor.
