You decide to move to Step One of your get-me-out-of-trouble plan. Step One is the cover-up. You need to hide what you've done.
If you've scribbled on the walls you could stick paper all over them so that mum can't see your scribbles. If you didn't tidy your room, you could quickly shove everything under your bed. If you punched your brother you could masking tape his mouth shut so he can't tell on you.
You put Step One of your get-me-out-of-trouble plan into action, but it doesn't work.
Mum has seen the evidence of what you've done and now it looks like you are going to get into more trouble than ever.
Do you:
Admit that you've done the wrong thing, say sorry, and quietly accept the consequences,
OR
Move to Step Two of your Get-Me-Out-Of-Trouble plan?
