Well I thought it was lovely.
he just said a quick "hello" on the doorstep, mentioned the "letter" that my son had sent (a piece of paper to fill in with your name, siblings, hobbies if you wanted), and that he would see him when school started.
It wasn't official, just something he did on the off chance.
So if you missed him you did.
Schools a big deal here.
The first day is always 2days after school has started back.
There´s an optional church service, then off to school.
Children sit at the front of the hall, parents/GPs friends & other rellies at the back.
HT does a welcome speech, then there was an entertainment by the children who started the year before.
Then the class teachers introduced themselves & called out the names of the children in their class, who then followed them off to the classroom whilst onlookers clapped, cheered & wiped away tears.
Whilst the children are in class for an hour or so, parents mingle & there's food & drink.
Then the next day they start with the full days.
It's the same for starting secondary, although no church service.
