I have got this theory.

Ever wondered what your child's class teacher thinks of you? Then take a look at what item you have nominated to bring in for the class Christmas party.

I believe that little slip of paper that arrives in book bags or backpacks this week reveals a lot about what the teacher thinks about you.

I brought it up with a couple of teacher friends who just laughed but refused to confirm my suspicions.

This isn't an exact science, you may not agree, but here is what I believe your nominated food item reveals.

Sandwiches

You are a trustworthy parent who always delivers. The sandwiches takes a lot of preparation, is a key item for the class buffet and can only be given to someone who won't let you down.

Chances are, you always volunteer for school trips or to help out in class and you are most definitely on the PTA.

Cheese and pineapple on stick

This is a job for the arty parent whose child's homework always stands head and shoulders above its peers for sheer creativity.

They will be uniformed cubes of pineapple and cheese possibly presented on a Pinterest-worthy melon shaped like a crocodile.

Crisps

Probably the parent who has to write apology letters for sending their child's forms in days late, forgets its forest school and is always running a bit late.

The fact you can pick them up from any local shop or garage on the school run is probably a blessing in disguise.

Biscuits and cakes

These should be delivered by the sensible parent whose child always wears thermals for forest school, knows how to correctly hold scissors and has never turned in a piece of homework late.

The last thing teacher needs is someone dropping off e-number-filled goodies to send the children, already hyped up for Christmas, over the edge.

The parent will also check, check and triple check they do not contain nuts.

This is as far as I have got.

So what did my children's class teacher as me to bring? Crisps (fair cop) and sticks of carrot and cucumber.

I'm baffled what this could mean.
