Robert Walser from Wikipedia:
Robert Walser is the writer of the ethereal. You read a paragraph of his and you float because what he says is completely evanescent, it disappears into the thin air like water between your fingers. In Walser you aren't going to find deep, solid thoughts; you're going to find feelings so light as the thread of an ant on the palm of your hand, sensations so frail as gossamer. Every character of his is tender, delicate; there aren't any villains, any bad people, only misunderstandings, venial mistakes and involuntary errors.
You know what a feelgood film it is: watching it you smile, you laugh, you even cry your eyes out, but at the end, after the catharsis, you feel happy and relaxed. When you're reading Walser, a smile is all the time outlined on your mouth; you'll never cry, or perhaps you'll cry because what you're reading is so lovely that your heart will ache.
It's a bit difficult to tell what happen in his novels: the plot isn't important at all, you only have to pay attention to the characters, and, it doesn't matter what they do, you fall in love with them.
Quotes by Sebald:
"His prose has the tendency to dissolve upon reading."
"The point of everyone of Walser's sentences is to make the reader forget the previous one."
"In all his prose works he always seeks to rise above the heaviness of earthily existence, wanting to float away softly and silently into a higher, freer realm."
