I am sure Laurina is annoying to live with in this tight setting - but gosh I hate seeing her being ganged up on and talked about in small groups behind her back. I don't think it is doing Jo Beth, in particular, any favours to be acting this way.
I would find Bonnie harder to live with, with all the endless dancing on that bloody board they've brought in this year; or Val earlier, barking out the proper way to do charades. Poor Laurina has slightly off social timing in her speech and likes to pluck her eyebrows (I can relate!), but is a good old stick in so many other ways. I appreciate Shane pointing this out, now and then - or it could turn into a spiteful schoolyard Lord of the Flies scenario, with the entire camp feeling justified in targeting and extruding Laurina from the fold.
