Saga of the toilet seat

A while ago we had the bathroom done and it all went very smoothly. There was only one slight hitch- one of the special soft-closing hinges was missing from the toilet seat.

Then we spent the next month and a bit trying to get a replacement - wrong piece sent, lost orders, that kind of thing.

Finally they send through an entire replacement seat - which meant entirely replacing the existing seat.

Now, to borrow a line from Nick Hornby, I'm not the cleverest guy in the world but I'm certainly not the dumbest - and yet it took the best part of four hours to fit the new seat (that includes time for various tantrums).

I blame most of that on the fact that these are all the instructions you get. Do these make sense to anyone?
