DS was staying with my dad last night who had been loaned Mama Mia from a friend for them to watch. I asked if it was suitable and I think my dad wound me up on purpose saying 'Oh, but he'll like the songs' and I replied that I knew he would but would the film be ok for him? I felt my dad deliberately misunderstood what I was saying and repeated that ds would like the music. I checked some reviews on the internet and many said there were references to sex etc so I rang to say I would prefer him not to watch it until I had seen it so I could check if the content would go over his head or not. I think I made the right decision but it is niggling me that I spoiled the evening my dad has planned with ds.Was IBU?
