Walking in Paris with children is terrifying.
I am constantly afraid I'll lose one and won't know how to ask for help finding him.
I don't remember how to say "sorry," or "excuse my child, please," when they run into someone because they're not looking where they're going.
I can't say "watch out!" when they're about to cut someone off.
I'm terrified they'll knock someone over or get hurt themselves. My brain is totally fried with jetlag, and I can barely think. Let alone get around.
Like I said... walking in Paris is easy. Navigating will take some getting used to.
