He asked me why I skipped detention.
Why did you skip detention?
I like to sleep in my bed and I like to watch TV (on the computer).
Detention is usually given because you broke a rule or guideline. Skipping that punishment will only be worse if you ignore it.
I'm not afraid of getting consequences.
You're going to get caught sooner or later. It's better if you do your detention and get over with it.
