Tell them that you're a nudist now.

"Excuse me, young lady, but could you explain why you aren't in school in right now ?", your father questioned you.

"And more importantly, why were you dancing naked just now ?", your mother added in.

"Well...", you say while thinking of an excuse for them. "As for the first, i guess i simply oversleept, and since the school doesn't allow students to enter an hour pass the entrance time, i had **** but to skip today, i guess ?", you lie.

"Oh well, that's understantable, but make sure to ask for any missing homework tomorrow", Replied Dad , since it looks like he cares more about you missing school than to being naked.

"Yes, But that doesn't explain your state of dress, or lack of thereof", your mom said.

"Emmm.....", you say while thinking of an credible excuse, since they aren't obviously gonna like the fact that you're a closet exhibitionist, "I guess you could say, that...i like being naked", you respond.

"What, are you serious !?", your mother replied.

"Well...yes.., i mean, the thing is, that...i decided to become a nudist, you know ?, those people who like being naked...", you say that, as it was the only thing you could think at that moment. Upon saying that, you look at your parents faces, who by their look, are still processing in their heads, what you just said.
