Piano revival

I've been meaning to start playing the piano again (I've had lessons for four years and played a while after that, but it stopped as soon as I went to university) for more than a year now, ever since we moved into this big(ger) house. Somehow, I never really got round to it, until a couple of months ago I heard someone play the Amelie song Comptine d'un Autre Ete in public, and I decided I really wanted to play that song. Which meant getting a piano, and learning to play again.
I went for a digital piano*, as you can plug in headphones and play all hours of the day without disturbing other people with your awful hammering. Also, it never goes out of tune, which is nice. After a short online investigation into the really beautiful but very expensive big brands, I eventually bought a Casio CDP-100, because apparently it's the cheapest piano that still has a reasonably okay sound and touch sensitivity. I bought one second-hand via the Internet, and it has been sitting in one of our upstairs rooms for a week now, because I didn't have my sheet music and after 10 years cannot play any song from scratch apart from 'Twinkle twinkle little star'  and that gets boring after a while.
But last Wednesday my parents came to visit and brought with them a towering stack of piano books; who knew I had so many? Easy songs and classical songs and jazzy songs and very recent pop music songs all combined into my history of piano lessons. I used to love all the country tunes and melodic musical wanderings before I turned to more recent and less classical stuff. Looking back, I think this was the sign that I wasn't really interested in the whole piano thing anymore, but right now I can't wait to get back into all those classic classical pieces.
So today was the first time I tried some of the old songs again. And it went surprisingly well! I could play each and every song of my first 'real' music book without problem, and even in the proper time. Now these are songs where you don't really have to move your hands about, and all the notes have the correct finger position above them, but still, it surprised me. Then I tried some more difficult things, a menuet by Mozart that I'd played at a recital, and that one went quite okay too, a bit slower and hesitant, but still pretty nice. With some of the moves, it was like my fingers still remembered the things they used to do, and just went along in a stream of memory movements.
After a while, my arms and especially my fingers became pretty tired (strangely enough the thumbs seem to go first, probably because you don't really move them when you're typing, which is the only similar movement they've been getting for 10 years), so I decided to call it a day. But still, a whole hour of reviving old songs and playing pretty decently, I'm positively surprised at how well I am actually still playing. And as they say, practise makes perfect, and I have a whole weekend of practising ahead of me!

* I've been getting some questions as to why I call it a 'digital piano' and not a 'keyboard':  because the two are completely different things. A digital piano is basically a piano that produces sound digitally, meaning you can stick in some headphones and not bother anyone with your music. But it does have 88 keys, which are pressure sensitive and weighed, so it takes the same effort and effect as playing a real piano. Keyboards have fewer keys, which usually aren't pressure sensitive and take very little effort to press down. It's a bit like the difference between a type writer and a computer key board. And as I plan to buy a real piano sometime in the future, I felt it was better to buy a proper (and more expensive) digital piano than they keyboard substitute.
