My parents have told me something quite serious about my nan who is very elderly.
It's caused a lot of problems in the family but doesn't involve or impact on me.
The person it does involve lives with my nan and is there occasionally when I go to see her with my daughter. We stay 20 mins and just chat. My DD adores her.
My parents told me this info because they want me to disown my nan and stop DD seeing her.
They said they told me to 'see where my priorities lie'. I laughed and said I'm not taking sides and will continue to see her.
There is no risk to my DD so why should I stop just because their not happy. 
Is it an ultimatum and should I ignore?
