So you are travelling, let us posit, on a train. Because you are this particular kind of fool, you have with you a pair of children. Because of your poor parenting or a couple of bad hands dealt by nature, your children are a pair of hapless morons.
You need to get off at the next stop. Because your children are, as mentioned, hapless morons, you are skeptical of their ability to move from their seats to the door in the time that the train is stopped at that station. Consequently, you get them up before the train stops. Good for you for forward planning.
Except that you have gotten them up in time for this station. And, not only that, but you have, after cleverly waiting until everyone else got off the train and the passengers waiting in the freezing cold have concluded that they can get on the train, shoved your kids into the vestibule between the cars.
Why? Why is this your plan? You have now made it impossible for anyone to get on the train. You have confused the conductor, who thinks you're trying to debark. Now you must turn around and go back into the train car, which will take you several minutes because you must corral your imbecile children, whose reaction to this setback has been to spin slowly and stare blankly into space. You are the worst, and the people who wanted to board the train are now unnecessarily cold and very annoyed.
On a side note, you appear to have been French. This is not even acceptable behavior on French trains. For your sins, I suggest a cage for your stupid children and a chauffeur with a bad attitude and a slow car for you.
