"I'm not sure," you say to the woman. "I don't know the first thing about being a girl, but I...well, I'm interested." You blush as you admit it.
The woman puts her hand on your shoulder. You react with a step back, but stop yourself before getting too distant. She keeps her hand there and steps forward in response. Her eyes are gentle and reassuring.
"There's nothing to be ashamed or afraid of," she says. "People need an escape from their lives sometimes. Even an escape from themselves. You're not the only one who's ever come in here and said they wanted to be a girl for a day. Or longer."
You still feel embarrassed, but your anxiety subsides. You need to get more comfortable with the new thoughts passing through your mind. Wouldn't it be fun to be a girl? You can have a brand new identity, of your own choosing, where you could return to normal whenever you wanted.
You nod to show her you understand.
"Okay, so let's go over to the ladies' section and find you a costume!" The attendant removes her hand from your shoulder and takes your hand, leading you towards the section of the store where you took the school uniform.
