I remember my own cuticles looking just as ragged when I was Ingrid’s age. And I have distinct memories of being told to not grip the pencil so hard.
The helpful advice made no difference, so I don’t try to pass it on. But years did: I no longer have a death grip on my pens.
My fingers and nails on the other hand honestly do not look much better now – I keep my nails short and neatly cut, but my cuticles are not pretty and during the gardening season there is often dirt under my fingernails that I just cannot get out.
