When the snow is deep and Mrs Williams runs out of jelly-babies, it is time to invent something to move the snow out of the way.
Some snowdrifts are just snow, but some have more than snow in them, and they must not be ploughed aside, even for the sake of the General's new teeth.
Some fire engines will go absolutely anywhere, so long as they don't get stuck. Then they must not be too proud to ask for help.
Pulling sledges up the hill can be quite fun, if you are strong enough, but it can be even more fun sledging down the hill again - if you have a sledge.
When all the latest technical equipment cannot pull you out of trouble, perhaps it is time to get help from more old-fashioned pushers and pullers.
Some engines are very particular about what they will or will not be willing to drink, for the sake of who or what happens to be in the drink.
We must always do what we can to help others, even if they do chose to build their houses in such extraordinarily silly places.

Engines don't always do what you would expect them to do, but luckily they are very rarely stolen by gangsters.
Even the most difficult feats of engineering can be achieved, especially if they will help a friend to join in the fun, and also get very wet.
