In contrast to the other children and in contrast to the author of this text, grid paper wasn’t inviting for me, instead it was feeling like oppressively giving me direction that I don’t want. I would ignore the grid and see the grid as something like dirt on the paper. Only a bit later I discovered that I could buy smooth and dense note paper that was completely blank. Ever since then I mostly use 100 g/m2 white A4 paper; rarely also A5.
I love the liberating feel of white paper. After a few years I even learned how to write justified text on blank white paper, it feels very satisfying.
