Got to my son's nativity slightly late (as ever) but just before curtain up. My husband and I sat in our pre-booked seats and the bloody irritating alpha mummy behind us shouts 'oh for goodness sake I cant see now' then spent the entire performance loudly sighing, tutting and asking her husband to take photos for her as she 'couldnt see anything'. I felt awful and I know its the season of goodwill but really wanted to punch her!
