When a man is sick or hurt, all manliness goes out the window, and all he wants is his mommy. So just for today to wrack up some good girlfriend brownie points [you DID just check out that hot clerk at Costcos, don’t lie.], take care of him like his mother would.
Tuck him in, give him kisses, feel his forehead, and make him soup. Baby him a little bit and make him feel warm and comfy and full of warm and fuzzy love. He’ll appreciate it and know that you truly care.
Just don’t let him get too used to it.
