Beautiful writing, but I can't say I understood everything. You'd probably have to be an Estonian of the right generation to get the most out of it - which is OK: writers don't have to cater to everyone, and in any case, cryptic speech is central to the “plot“ (to get around surveillance) - hence the photo featuring examples of surreal WW2 coded messages: https://en.wikipedia.org/wiki/Les_Fran%C3%A7ais_parlent_aux_Fran%C3%A7aishickleb...
NB: I chose this French-centric (sorry!) photo because some of the things characters said reminded me of those coded messages, but the book is set in 1968, at the time of the Prague Spring, and not during WW2. 8mo
