I have no idea!

We laugh all the time cause it’s an on going joke now. I say ‘I have no idea’ all the time cause I think the injury has effected my memory and made me unsure about a lot so as have been saying ‘I have no idea’ about things to Linda since I got home, if I ask her a question in the morning when I’m getting ready her response is jokingly ‘ I have no idea ‘ 😉😝
