Sometimes it can be difficult to explain the joy of having children, especially when they’re busy fighting, ignoring the most simple of requests or just being plain loud in that way that kids just are.

And sometimes it’s not difficult at all.

I was away in Dusseldorf – and pondering the lonely existence of the business traveller – from Tuesday to Friday this week, restricted to snatched phone/video conversations and text messages. And then Isaac, completely unprompted, went off and produced this all on his own.

I don’t think this needs explaining at all, does it? I love my kids.
