Only a few days ago, the leaves were newly unfolded (or "mouse ears", as we say in Finnish), and now they are full-sized. I don't remember this happening so fast ever, but then my memory (and I maybe everyone's) is quite short.

Actually, there is a saying in Finnish, "miesmuistiin" / "in a man's memory", referring to something only happening once in a lifetime. But - and this happens usually - then someone shows statistics or other evidence that this rare event happened previously only a few years ago. So short is "man's memory".
