Last year, when the power mower was broken and wouldn't run, I kept hinting to my husband that he ought to get it fixed, but somehow the message never sank in. Finally I thought of a clever way to make the point.
When my husband arrived home that day, he found me seated in the tall grass, busily snipping away with a tiny pair of sewing scissors.
