TEMPER
Little Molly had been very trying all day. That evening, when her grown-up sister was putting her to bed, she said she hoped the child would be a better girl tomorrow, and not make everybody unhappy with her naughty temper.
Molly listened in silence, thought hard for a few moments, and then said, wisely:
"Yes, when it's me it's temper; when it's you it's nerves."
