Decisions, decisions

I got a call from the house builder yesterday afternoon; 'Hello, this is urgent, everything is going well, we had a site visit that morning, all the workers thought it was incredible, the trench for electrics is imminent, Telecomn are primed, but ... you have to decide the colour of the water tanks and you have to decide now!'

Wow. What a decision. 'What are my options?'

'Black, beige, two greys, blue, white and .... ta-da ... three greens. Why not go the website and have a look?'

So I did. 'How about Mist Green?'

'That's the one we think is most appropriate.'

Why didn't he say that in the first place?
