This is one of my most favourite books, one that I truly think everyone should read.
It really puts a lot of your life into perspective, it brings forth the idea of momento mori - which is even cuter because 'morrie' and 'mori' sound the same.
This is one book I gift my friends the most, because I genuinely want everyone to read it. This is, I think the only book that I've cried reading the ending of, despite knowing what was going to happen briefly.
