Rocky has discovered bogies.
He's also discovered that bogies can be picked and are sticky.
He has also learnt from somewhere that flicking bogies at someone is hilarious.
And that wiping them on Mummy is even more hilarious.
Oh and that chasing people with them is even funnier.
I would take joy in knowing that it's just a phase but Kyd I still doing it and he's 12.
Boys are gross.
