I lost Mum 18 months ago so I'm going into my second Xmas without her and it's so tough. So to watch someone be so openly condescending and downright mean to their mum really infuriated me. Not everyone has a great parental relationship I get that, but I'm jealous of anyone who still has their mum and angered by people, like Lydia, who take it for granted. Don't take it for granted and don't demean her.
Side note, if she was aiming for some sort of country chic look, hun, us real country folk are usually in muddy boots and thick coats that have random crap like hay in the pockets
Oh and feed your cat somewhere else
