Remember at school when your teacher wasn't a normal human - but a teacher?

They would be there to show you how to multiply and spell - like a real-life dictionary and calculator - but when it came to finding out personal information about these beings, it was always baffling.

Two weeks ahead of this year's KS2 SATs - which begin on May 11 - we thought we would revisit the days of being a pupil and recall five things that were utterly shocking to discover...

My teacher has a first name

'Did Mrs Spencer just call him John? Who is John? But I thought he was called Mr Martin?'

What. That is so weird.

'Mr Martin's' whole character is now put in question. He is not who we thought he was. Does he have two names? Two identities? Even his face looks different now...

Teachers have homes and do not live at school

The idea of a teacher being out of context was totally incomprehensible.

So, when they mentioned where they lived or you saw them driving away from the school gates, a silent intrigue would fall upon the playground.

Where are they going?!

Mr Martin wears jeans in his spare time

Did you ever bump into your teacher at Sainsbury's and feel totally perplexed at his or her attire?

Jeans and trainers look highly odd on teachers - surely they wear suits to lounge around at home as well? No? Also, how funny that they go to the supermarket...

The fact teachers can be romantically involved with someone

Finding out your teacher has a wife, husband or partner was another bombshell.

Trying to imagine them being soft with someone and not strict was too difficult, let alone the idea of them showing affection.

Teachers are allowed to have children too

Wow, they have their own kids! So we are not their children.

I wonder how they treat their children? Do they test them on their times tables constantly? What do they talk about? Do they get 'told off' when they do something wrong?

Surely their children must be really clever if they have a teacher as a parent.

So many questions...
