You know how...

Congratulations - you had the foresight to install a recess in your new shower instead of using an ugly shower caddy that will inevitable turn into a rusted frame after a few years. But there's a slight problem.

You're using the toilet in the bathroom. You've locked the door. You know it's locked, don't you? But now you're second-guessing yourself and...what if it's not locked and somebody walks in? You'll be caught - literally - with your pants down.

So you've forked out a reasonable sum of money for solar panels on your roof but they don't seem to be performing to the maximum advertised capacity, even on a bright sunny day. Why is this?

It's almost time for bed when the first sound of rain patters on the window. That's nice, you think, as you snuggle into your blanket on the couch and...oh crap the clothes are still on the line!

You can never seem to remember which knob lights which element on your stove top. Now after a few years into your new house, the symbols that indicate the element's position next to each knob on the face of the stove are starting to wear off, making matters worse.

You flick the light on. No, wait...that's the wrong light. Frustrated, you turn that light switch off and then turn on the actual light you wanted. No matter how many times you use the light switch, you always seem to hit the wrong one more often. Why is that?

You have a nice flatscreen TV...that turns out to be really only usable at night.

So the cable on your phone charger head juts out to the side. You are in a rush, your phone's almost out of battery and you're waiting on that important call back from the clinic.

Your AC is cranking in your living room, but somehow it just doesn't seem to be doing its job. You look around and realise the cool air is unnecessarily leaking into other parts of the house, like the hallway and corridors.

It's midnight, and after a few bottles of wine your guests head to the guest bedroom. Well, "guest bedroom" is putting a positive spin on "our junk room that we cleaned up before you got here because it has a fold-out sofa bed."
