I know I'm gradually turning in to a grumpy old woman but....
Parents that yell from a distance to their kids, usually to stop doing something or start doing something. Then after the 5th or 6th attempt at screeching at them resort to idle threats.
One example: Mother and daughter in a park, Mum sitting on the bench, daughter sitting on the grass. "Doris,put your i-pad away were leaving" ( as Mum continues to use her phone)
After the 5th "Put the i-pad away" ( As Mum continues to play with HER phone) Mum resorts to "If you don't put it away I'll take it off you" Another 5 times......
All I want to do is get up from the other end of the bench (sitting enjoying the sun last week) yell at both of them " Both of you Get off you bloody appliances and piss off"
AIBU or just really grumpy at the moment
