We've all heard it over and over again, bless her!
When we were kids we had to leave our outside shoes at the back door. Three pairs of Wellington Boots would be lined up for mum to make sure they were clean before she brought them in.
As an adult and parent, my own kids leaving lights on in the house used to bother me - A LOT!
I'd give off day after day.
Seeing the house lit up like a Christmas tree from the other end of the road, and everybody in the house in the one room, would send me into a huff. I'd make the children leave whatever they were doing, and send them to all parts of the house to turn off lights that were on - but not needed, in rooms that were not being used!
One day as I was coming down the stairs after turning empty bedroom lights off DURING THE DAY - AGAIN, the thought suddenly struck me that there'd probably come a day when the lights wouldn't be left on.
That day would be when the children had "flown the nest" - university, jobs, marriage.
I determined from that point on never to complain about the lights again.
The day when lights are not routinely left on arrived. The boys lead their own lives across the water. I miss them - and sometimes even wish that the lights were still on :)
