I must remember to look through a Thesaurus for a word that means something like "time spent in the pursuit of something that seems to hold meaning, but turns out to be trivial in the extreme". If there is no word then surely it is just waiting to be discovered in order to desctibe the pasttime of making small boats from flotsam.
Note to self: must check the Meaning of Liff.
Can't be long now. No more than a week, surely.
