When the instructions say: "Gently pour over the lightly whipped double cream", but you've already stirred in the standard cream, it's too late.
It'll still taste great, but it's not quite what was intended. So as long as you were looking for something generally delicious, not something specifically fantastic, you're happy.
There's no instruction manual for a home. There's no compiled guide on how to find, rent, buy, decorate, renovate, design, or live in a house.
But if you have a home, it's still great.
The trick for long-lasting satisfaction isn't in making sure you've memorised the instructions. The trick is to have some generally reasonable expectations and hope for more. Instead of expecting a particular perfection.
