Omg, I'm reading this stuff and I'm stunned.
Many not agree with me, but I think 2 x 3 year olds at a funeral is madness. I understand it was their granda, but they have no understanding of what going on. I guess she left them peer into the ground at the graveyard too while they lowered the coffin, no doubt Fionn kicking off again. What would have been wrong to say he was gone to the angels? My own kids were similar ages to the twins when my mum died, and we kept them from the church and graveyard, brought them back later and showed them that it was nana's garden for us to visit and be near her.
And as for Sean, I've always thought the apple didn't fall far from Julie and her mam. What a disgrace to be pissed like that.
