Obviously, Mark was really confused. He was now dressed like a girl his age and people were treating him like a girl his age.
But then a thought occurred to him. Why wouldn't people treat me like that? He became confused again, but then his attention was diverted. His eyes wandered over to a sign in one of the storefront windows. They're having a sale at that women's apparel shop. I've gotta check that out! I bet they have great deals.
He smiled, all thoughts about how shopping was boring and how he only intended on buying a video game and leaving the mall ... all of those thoughts disappearing from his mind. He headed into the shop, intending on buying several cute tops and miniskirts.
