I loathed Peig ....until I spent a month in the Gaeltacht actually seeing the Blaskets, walking the places that she described and seeing where she lived.
After which, I kinda got her life...such a harsh time.
Just like you loan, as an adult, I admire her. But as a 16year old, a lot of it washed over me.
Songs adding to what notWORK says, it's a text that every child for generations had to read.
A bit like, mutual bonding over dissecting King Lear.
We were all traumatised by the language she used (i.e. not basic level Irish) 
It's basically survivors' black humour.
