I lost my clothes at my friend's place...

You think that the best way is to tell the truth. So you begins your story with going to Richard's place and losing your own clothes.

"I have only one set of clothes left, so I borrowed his sister's clothes as we're about the same size. Since his sister doesn't know, I took few sets from the box when i left. So I can wear at home. It not my fault, really..."

"Are you sure you're not cooking up any excuse?"

"Yup"

"I believe you, do you like wearing women's clothes?"
