I have tried to work out a solution to Rafa's math problem about the worm that pierces books, and I must confess that I failed. Right, I'm not very good at maths, but I am good at languages so here is a bit of language comparison.
In English, we say that you are a "bookworm" if you like reading very much, you spend your time reading, you talk about books all the time, you are an avid reader, etc. However, in Spanish, we say that you are "un ratón de biblioteca". Why do you think the animal related to books is a worm in English-speaking countries (Anglo-Saxon countries) and a mouse or a rat in Mediterranean countries like Spain?
In other languages:German: Bücherworm (like in English)
French: rat de bibliothèque
Italian: topo di biblioteca (topo is mouse in Italian)
Portuguese: rato de biblioteca
In any case, are you a bookworm?
