ok nobody has answered yet but will tell you whats in my household. Actually there are FOUR fridges (only two work though)
One fridge or fridge/freezer has food in it like icecream (very important this summer) , 'baby boomer' milk, cheese and butter. I dont think we will ever run out of dairy as dad is forever buying it like he would die without it. Or the entire country would collapse, because basically it is the land of milk and honey (more milk than honey though) . There is always a tin of catfood.
The other fridge is not working but is a pantry with jars of spices and pickles and I dont even know what. Ask mum about that.
Then theres another fridge in the garage that is actually a freezer and Im sure my rhubarb is in there must be very old by now but its frozen so must keep forever. I think theres some frozen tangelo or lemon juice in there.
Then theres another fridge that is out in the street I look after and that is full of BOOKS.
we do stick stuff with magnets on the fridge, ours has a gardening calendar and a tide calendar and various phone numbers.
I saw one of my friends fridges and she had covered hers with family photos, another friend had postcards from around the world. My brothers have absolutely nothing on their fridge because they are boring! I think they just like the look of metal as their fridge is silver metal coloured... its not even whiteware. It matches their metal coloured oven and dishwasher. When I look inside it always seems to have grapes and beer in it...and leftover food growing fuzz. No judging! Its just whenever go there they never seem to have any food (that is edible) and so if we are to have dinner we need to do a big shop beforehand or order something in.
As its summer here it would be great to have one of those walk in fridges they have in takeaway/restaurants just to hang out for a bit. haha I can dream.
childrens books always seem to have magic school buses, magic cupboards under the stairs, magic wardrobes...but I have yet to read one that is about a magic fridge....though with the popularity of Disney's Frozen you woukd think people would pay more attention to just how magical a fridge really is.
