Should I take the car?

What a grey day.
My dilema is...
Should I take the car or walk?
One minute it's freezing cold, windy but sunny... the next minute it's freezing cold, windy and chucking it down.
Walked Honor to nursery and got there an hour early because my brain has stopped functioning. Turned round and walked home again. Got wet but nothing too bad.
Left an hour later, got wet going there again.
Coming home got flaming drowned!
Had to peel my jeans off me shove them on the radiator to be dry in time incase I do decide to walk and pick her up.
The reason why the car is such a dilema is because I have to load it up with the other 2 kiddies, unload it when I get to the car park. Put them in a buggy, pick Honor up, get back to the car and unload them all again. Get them all strapped in, drive home and unload.
Works out quicker and less hassle to walk.
HHhhmmmmm what to do????
