I’ve written about him before.
Can I just remind you that despite the burden of carrying an egg and caring for it at all times:
HE IS A TEENAGE BOY (note the shouty capitals!)
Having this egg does not preclude him from normal teenage behaviour.
This may be hard for you.
I know it is hard for me.
He can be angelic but:
He will break the rules, despite the egg!
He may be rude, despite the egg!
So, please do not treat him differently, because of the egg!
