ein: Humor is universal, even when there exists an absolute language barrier. Be surprised at it, roll its sweetness around on your tongue, then pass it on.
deux: In every locale, there has been at least one kind stranger who opens a door, helps lift a stroller, offers to give up a seat on the bus, or entertains my wailing child with a silly face. It doesn't happen every time I need it but definitely more often than I expect it to.
tre: People in all the places we've been raise their children with diapers, formula, baby food, and other basic necessities, which makes forgetting a staple less upsetting, more fixable.
neljä: Even if you're pregnant and/or nauseated, or the pickiest eater in town, don't let the local cuisine stop you from going somewhere. Get to a supermarket; most people in the world eat crackers, dried fruit, or whatever else is on your not-so-big "consumables" list. I'm a huge supporter of eating locally when in a new place, but
some situations just call for crackers and seltzer water.
