I love that they've taken a real interest in history and feel no need to step in and end their violent imaginary play. (Although we have spent a great deal of time focusing on the fact that Germany is now our friend, and we love all German people - a truth they cheerfully accept).
It has only become a little embarrassing at the park, however, when they yell ever-so-loudly, "Look out, it's a German. Kill him! Kill him!"
But I bury my nose in my book, try to look the other way, and make sure to call Oma and Opa when we get home and have a good laugh about it.
Wonder what we'll be into next?
