Denise's P.O.V

Well do I tell Britney, Joe, Nathan and Sarah or not. I mean Sarah is only four will she understand she loves her nanna to pieces I can't break her heart can I, Nathan might understand his six but his more into granddad than his nan, Joe is ten and has a good understanding but not a good as fifteen year old Britney got a great understanding, What do I tell them. Nothing is the answer
