At different times I've seen photos of swish houses where the en-suite has two basins.
Sometimes I've seen them on TV.
You'd reckon that I might at some point have stayed in a hotel room with this feature, but we don't stay in places that cost that much. Even in Asia.
I've always thought that it would just mean more work cleaning...
... but last night as I was wiping down the handbasin in our en-suite I reflected on the fact that two basins (as long as they were strictly 'his' and 'hers') would give clear evidence of who was the messy one who therefore is the one who should be wiping down the handbasin.
Same location, same amount of atmospheric dust and linty fluff, same degree of 'hardness' or 'softness' in the water. Different user.
How impressed was I to find a blob of toothpaste in the clean basin this morning?
