DST
This morning I walked the house, setting back clocks in each room to the new "winter" time. Darkness will come sooner, yet I know in six weeks, the sun will begin its journey to summer (gives me joy to remember that) and in March we'll again enjoy more evening light.
Setting the clocks forward or back was always an event for mom. When the change to or from DST occurred, Mom was terribly confused as to why she'd be picked up for church earlier or later than the week before. Somehow she had a speed bump in her brain that just couldn't quite understand the hour difference.
The grandfather clock, the stove, microwave, school clock, digital "voice" clocks, etc. --all were changed to DST and back as needed, and Mom, dear soul, eventually synced her internal clock as well.
