Do you ever get a day when everything goes well. Then the day it goes mammaries up !
A good day is :
All the traffic lights were green.
Not stopping at roundabouts as the traffic was light.
Goods in staff pleasant and helpful.The kettle is in there.Help yourself to a cuppa.
Not much congestion.But is really bad going in the opposite direction.
At load/reload places ,you are the only one there.
For a bad day,the opposite of all the above.
