Yesterday, we were at the doctor's office. An elderly lady was wheeled in by her 'older' daughters. I won't repeat what she said (for privacy) but she made a remark that prompted everyone within hearing distance of her to chuckle. Her daughters wore a look similar to parents of toddlers when their children say something 'cute'.
This morning I thought about it again, and realized toddlers and the elderly can get away with saying things that most of us will not because we have 'to be proper'.
