Sometimes, it takes removing yourself completely from the comfort you've known to know just how lucky and stupid you've been. Take water, for example. In the States, if you want it hot, it's hot. Our water heaters are huge. Here, not so much. They're usually anchored to the bathroom ceiling, taking some space in the shower. We turn the boiler on overnight, and then after our showers, turn it off. We usually have hot water to last the day, but sometimes not, so then we wait until 9 pm and turn on the boiler again. This way, we save electricity because it's more expensive during the day than at night. Now my showers are very quick!
Space is another thing not to be taken for granted. Our fridge:
See the olives front and center? Mmmmm. Needless to say, it cannot hold a ton of food, so we have to go to the grocery store more frequently than we do in the US - usually every other day. So far, I only really like shopping at the big big big grocery store that reminds me of Wal-Mart - the aisles are big enough that you don't run into scowling, scurrying people. It's a bit far for the big stuff though, so I have to resign myself to the fact that I have to go to a smaller grocery store closer to home.
