The same in Romania. In the 90s, everyone I know had to learn how to write with a fountain pen.
For me at least, I write horribly when I use a ballpoint pen, vs a fountain pen. Because the ballpoint slides on the paper much too easy, like on ice, and you need much more discipline to write nicely.
A fountain pen nib is generally more scratchy and feels easier to control.
My 2 cents anyway...
