...do not plan to bake bread for visitors, the electricity will go off when you need the oven.
...do not take your car where only a 4x4 should go, it may not like to stay there overnight and you may get muddy walking home.
...do not let your 69 year old mother do the gardening she wants, she will probably break her ankle.
...do not let the kids wear their gum boots into the house, the floor will require hosing.
However, do make lots of crunchies, have good hot chocolate on hand and cuddle up with the ones you love and read Paddington.
