Standing or lying

Spent a good hour today with the architect going through whether the tiles in the bathrooms should be standing or lying, and how far up the wall the tiles should go. I guess it's good that they ask these things, since I'm the one who has to live with it, but still. It felt kinda unimportant. Also turned out that the guy who advised me on tiles failed to mention that those I chose are not fit for the shower. So now they have to send me new samples, and once again I have to make a choice. I'm starting to believe this process is never going to be finished!
