My FIL sadly died last week, i didn't think his family were religious, but MIL has said there will be a "proper" ceremony at the crematorium, with hymns and prayers, i've always been an athiest, and have no idea, what i should do with regard to prayers/singing, do i mumble,sing/say the words or stay silent with head bowed (my prefered option) or is that rude ?
The last thing i want to do is cause offence to anyone at what will be a difficult enough occasion as it is
Please help mn'ers !
TIA
