On event horizons and being the last person in Munich

K: Mommy, where does the Earth end?

Me (sagely - this is an easy one): The earth is round, darling. It doesn't end.

K: Yes it does. I'll show you.

She fetches a small ball.

K: Now look, Mommy. (She finger walks around the ball.) If I go around the ball like this it never ends. But. (She holds up one finger to make sure I'm paying attention.) If I go this way it ends right where it begins. (Her fingers leave the surface of the ball in the direction of infinity.) See?

Wow. It's true - the Earth does end at its surface. I stare at my 6-year-old, thinking that she can already think in 3D and has just discovered event horizons. In a flash I picture presenting to the Acadamy of Physics, tall, blond, precise, wowing an audience of unkempt men in tweed suits. I feel a thrill of pride.

Although part of me would like my children to pursue useful careers like accounting or medicine (useful to me, I mean), another part would be thrilled to be the mother of this generation's Einstein.

Science camp here we come.

BTW, Ralf is gone.

No, not forever, just a long work week in California. It's vacation time and my girls and I are the last people in Munich. But we are not alone - we are feeding the neighbors' pets while they enjoy their family vacations.

K already gave the rabbits 2 week's worth of carrots, which they have consumed. They eye me hopefully when I go in the garden but I have nothing for them.

The shops won't be open until Tuesday, I tell them, showing them my empty hands.

They twitch their noses to tell me they understand perfectly and would I now please bring them some more carrots.

Yes, of course, on Tuesday, I answer.

I think the isolation is getting to me...
