Ah but the genius of such a list is that it can also cover things like closing windows, checking the gas cooker is off, watering plants... anything that you might later think "did I remember to...?", while flying to Indonesia.

You might have left your fridge switched on, but did you close the door properly?

Read somebody saying that they used their phone to take a picture of the stove knobs before leaving the house.

As a person who has returned to the house at least twice to make sure the burners were off, that resonated.

With LED lights, making sure everything is turned off isn't such a big deal these days. But, while I don't really sweat closing up the house for a day or so, it's definitely worth checking things like windows on a longer trip. There are definitely a lot of things you normally do on cruise control and it's nice to be sure they really happened.
