Why doesn't every house just have the same shower, same settings and same heat control?!
I was dog sitting last night and it's shower time for me. I don't have a shower at home and I'm excited! But can I fuck as get it to the right temperature!
Might google it and see if there's an online manual 
It's also a wet room so now I'm panicking that I will somehow flood the bathroom then open the door and a wave of water to just flow out and drown the dogs and me!
If that's not the worse part of staying at another house then add your own!
