One is tired.
Have you noticed - if you've had to do it yerself - that people looking after rather ill people behave like Mums when it comes to feeding themselves?
I mean - finishing off what's on the invalid's plate etc.
Lunch for convalescent: Salad, ham, bread - eaten at table wiv mat and cutlery and everything.
Lunch for Nursey: last night's leftover broccoli, and cold mashed potato - eaten standing up in kitchen and straight out of pudding bowl.
