My Left Knee Cracks

It is pretty constant.  If I bend my knees to be even with my students, it will crack when I stand.  Should I sit with legs crossed, the movement of that left leg will be, with no doubt, serenaded with the grinding of bone on bone.  If I stand and turn, it will pop – pop loud enough for all to hear.

It can jar the teeth. It can be a relief. It can be annoying.  It can be embarrassing. 

It can be painful.
