If we are talking about general things concerning ACTUAL living, the warmth of the houses is one of the biggest differences. No matter how cold it is, Finnish houses are warm, cosy, and inviting inside. In England, the houses are invariably drafty and cold, and the moist air makes it feel even colder than it really is!
When I think my life in England, I can honestly say that I simply hated waking up in the mornings. During the winter, I mean. Ok, it's not so easy here either, what with the winter darkness, but at least in Finland it's warm when I wake up in the morning. That makes it just that little bit easier to emerge from under the covers and start each day :)
Apart from the coziness indoors, the main thing I really miss from England is the food. Specifically, fish and chips (I know, how typical, but it's true!). And the ability to communicate. I also miss the morning milk delivery. Small things, maybe, but quite significant, too. Luckily for me, my wife wakes up at 5 am, milks the cows in the forest, and puts a fresh bottle outside the front door every morning..
I have grown deep roots in Finland, and I will always carry them with me. I just came in from the crisp winter weather, and will have some nice warm glögi by the fire. Have a great weekend, and be grateful that you only have to listen to this drivel from me once a month or so - the Lady of the House will hopefully be back in action tomorrow!
