DP is Indian and his family are Hindu. They are lovely people and are always welcoming to me, they include me in everything and are so kind.
Recently it was Raksha Bandhan. It's a festival where sisters and cousins tie bracelets (rukhi) on their brothers wrists for happiness. DP has a lovely collection of bracelets and DPs mum said next year when DS is older, his cousins can tie rukhi on his wrists.
My mum has took offence to this. "Why are you doing this?" "If we wanted to take him to church you'd moan" "are you converting then?" "Why is it you never followed my religion but someone else's is fine?"
When I asked why she's being arsey she told me she just wants to understand 
I should add she's not religious in the slightest, only goes to church at Christmas and hasn't bought me up religiously.
I don't get why she's annoyed by it?
