Kids are all different. I'm a bit of a hermit and my son is definitely of the same tendency. When we bought the place in Portugal my son was 7 years old and we turned the whole experience into an adventure. We bought a van big
enough to sleep in, took the ferry out of the UK and toured round France, Spain and then Portugal until we found the 'best' bit, in our opinion. Then we visited a few little places that were for sale and involved him totally in the 'decision' process.
The first place we looked at was too small, too near the village, and too tumbled down to really suit us, but he was happily exploring it and imagining himself doing all kinds of things there. We managed to drag him away to look at a bigger place further out of the village which had an intact roof and a good
water supply. I much preferred this one, as did my other half, and we basically agreed, quietly, that this was the one, but then encouraged my son to really let his imagination run wild with all the things he could do on the place. When he'd got himself nicely carried away with plans for dinosaur parks and donkey stables and
underground laboratories and tree houses, we called him up and asked him if he'd like us to buy it for him so he'd be able to do all those things he was dreaming of. His eyes lit up, so we told him to 'ask the lady' (estate agent) if we could have it, then when we bought it we put the place in his name with my partner and I both having lifetime use.
The result is that he's totally bonded with the farm, and although now he dreams of different adventures involving going to the States, or the Amazon rain forest, or Australia, his
roots are definitely on the farm and he'll always have it as his base, his roots to return to.
We were careful not to choose a place too isolated though. There is a railway very close, within easy walking distance, so he'll always be able to get on a train to 'escape' if he feels the need (he's fifteen now and might soon start getting 'itchy feet'), and conversely no matter where he is in the world he'll be able to find his way back again pretty easily. We're also only about ten miles from a city, so he doesn't feel like he's 'stuck out in the sticks', but rather that he's somewhere nice and quiet where he can do what he likes, when he likes. Attitude is important to how a kid interprets stuff - it has to feel like an adventure and a challenge, but not a trial. It should feel like
freedom, not isolation. And they need to feel involved and that they chose to be there, not like they were dragged there.
Ooops - that turned into a bit of a lecture. It's all just my own opinion based on my own experience, but I'm really glad that we did it, and I'm totally convinced it was the best thing we ever did for my son. But your mileage may vary!
