I really enjoy that book but it always makes me....sad? Nostalgic? I always feel bad for the protagonist, more so than for protagonists in his other stories. I should re-read this one I think.

The are remarkably a few Tichy stories which which are quite creepy. Including a couple of brain-in-a-jar tales.

Disturbing bits and comedy he always mixed. Memoirs Found in a Bathtub is pessimistic, kafkaesque but somehow funny too.

A friend that knew I'm a fan, showed me a few paragraphs from one of those stories you mention, without telling me the origin. I said they were too dark and bitter for my tastes, before realizing I had read that before. I first read the Diaries when I was 12 (and 13 the second book) when I wasn't so judgemental, just took what I was offered.
