The best part of Berlin was sitting at a cafe, slightly tipsy in the afternoon, chewing a giant wad of bubble gum and doodling on a napkin.

I glance up just as a little boy is being pushed by in a stroller, eating a cooking and munching like this: munch munch munch.

So I munch right back: munch munch munch.

And we both crack up like it is the funniest thing either of us has ever seen, as his parents push on, oblivious to our inside-munching-joke.
