.... ringing your mother up at work and confessing that you have neglected to inform her that there's a parents' evening after school, and the appointment with the history teacher is in half an hour
Telling your mum that Katy the girl who lived over the Road from us had by mistake taken DS1s year end school report home with her !! but by the way she has just left to go on holiday for a month to her nanna's in USA.
Climbing out of bedroom windows when you've been grounded.
Bringing your girl clothes and your make up to your friend's house to change into before going to the party because you know his mother (me) is too thick to realise that you're a cross-dresser (I thought he was a New Romantic).
Having to celebrate your 21st birthday when it's really your 18th because you've been going in that pub so long you can't let them realise that you were underage all that time.
pranging your mothers car..... and then totalling it, the first time you are allowed to drive it again after a three month prohibition for the first prang!
Telling your mother on the day baby daughter has stood on the dishwasher and demolished it that you have had your head shaved. It wasn't anywhere near as bad as she said because middle daughter prone to exaggeration but she got into BIG trouble anyway.
