Get ready to go out.
Wait outside the bathroom for half an hour.
Go out the front door.
Come in again. Go out.
Come back in.
Go out again.
Walk down the front path.
Walk back up it.
Walk down it again.
Walk very slowly down the road for five minutes.
Stop, inspect minutely, and ask at least 6 questions about every cigarette butt,
 piece of used chewing gum, dirty tissue, and dead insect along the way.
Retrace your steps.
Scream that you have had as much as you can stand until the neighbors come out and stare at you.
Give up and go back into the house.

You are now just about ready to try taking a small child for a walk.
