LMAO my bad

I am officially a bad mother LOL..I got reprimanded by my 16 year olds teacher today
A child in his class was being all mouthy to him, and he turned around and sucker punched him…( No, i didn’t laugh at that )
To which the teacher sent him to the green room….
Josh being  Josh proceeded to lock the door..
The teacher was standing on the other side calling to hito " Let me in, Let me in"…To which Josh responded with a wiggle of his bum, singing "Not by the hair of my chinny chin chin"…

He rang me fuming at this, and yep i did have a giggle on the other end of the phone…
Yeh ok maybe i should have held the giggle in, but sheesh it was bloody funny..He could have said so much worse..
I then had to go up to the school, and meet with the said teacher , and vice principal, whom i should add, had a slight grin on his  face aswell LOL….

Wat would you have said..Really ??..lol
