Berlin...

(Maybe the cat is trying to tell me something about "more attention"?)
...very soon Aldus and I are going for a "little-long-weekend-trip" to Berlin. I've been there many times ("typo" and study) but I've never been there with a child before. Although he'll soon be 12, it's probably far too early to show him my favorite bar. And shopping is not exactly his favorite...so any good ideas? Anyway we are looking so much forward to that trip...(hope the volcano behaves!)
