Finns are a little down on their language. They don't really see it as important, but at least as long as you are in Finland, it is a very important language. Hell, it can even save your life. Take this sign at the Helsinki Zoo:
It is in Finnish and Swedish. It is a warning that the lions are dangerous and to not stick your hand past the fence. The warning apparently is needed because the cats sit right at the front and do look very docile. Of course they look that way until they know that they can get you. I have no idea why this sign is not in English as many other less-important signs are.
So consider yourself warned not to try and pet the lions. Not like any of us need such a warning.
