You were with your roommate, Joe, and when he got out of the shower you noticed his hair wasn’t properly washed. So, you waited until he got into his pjs, since it was already 10:00 pm, then you asked him if you could wash his hair. Which he agreed to.

Joe was leaning over the bathtub, while you put shampoo in his hair. “Oh- and thanks,” Joe said, wiping water from his face that was getting on him while you washed his hair.
