But hey, some people say that you can never really learn a language unless you live in an environment where you have to use it all the time. :D
I know families who have lived in Finland and moved to England or France when their children have been really young. The parents wanted that the kids learn to speak Finnish but they didn't learn the real R in another country so the parents sent their children in Finland as exchange students. 8D

Ahem, yeah. My piano has never been in tune so... :D We actually downloaded a program which listens to the sound of a string and tells if it's too low or too high. We can be deaf and still the computer tells us if our guitar is in tune or not. XD
