Crime scene

Putting away some garden furniture....
Leaning into shed put left hand on door lintel...
Saw nothing - but sudden excruciating pain in left index finger...
piriton, paracetamol, soaked in vinegar, and anthisan ointment...
half and hour, and good recovery...
an encounter with an insect of the order Hymenoptera and suborder Apocrita...
shows that summer is not all icecream and snoozes....
