I have mentioned this before on this forum but for those who don’t know the clocks in my house are a nightmare due to Mrs B and her time keeping. I employ a time shift system.
She is convinced that from alarm off to exiting house for work is only 30 minutes. Wrong! But I was never able to convince her. After too many late arrivals at work I set my plan in motion and it has worked for the last 6 years.
Her bedside alarm is 20 minutes fast, next is bathroom clock at 15 minutes fast, then kitchen at 10 minutes fast followed by lounge at 5 minutes fast and exit front with clock at right time.
She has never been late for work since but still insists that it only takes her 30 minutes to get up and get out! It is and always will be 50 minutes.
Also helps when we are due somewhere and she is getting ready in bedroom as her clock is 20 minutes fast.
