This astromical dispute about Pluto is coming at an awkward time for us. The lad has just got interested in space but isn’t old enough to start sniggering at Uranus, though I’m sure that will come soon enough.
We bought a mobile of the planets a couple of months ago, though with our usual procrastination, we are yet to hang it. But I looked and we’ve lost one – I think it’s Pluto, so that’s a relief.
