In her own way Mrs M decided to make my earlier post about pain in the night a self-fulfilling prophecy. Last night she had a back spasm and kicked me in the bad knee. You can't begin to imagine the contortions necessary to get from her side of the bed to kick me on the further-away knee.
Still (which we weren't) I commend the dance we then carried out as one partner back-stretched and the other knee massaged both screaming the while. It needs a name I feel. You may laugh now.
