I heard once that the average male speaks 2,000 words a day, while the average female speaks 7,000.
My wife interprets this as meaning we are allotted 9,000 words between the two of us. She therefore begs me to keep mum so she can take my 2,000 words for herself.
Normally, I don't mind. Two thousand words seems like too many anyhow. Besides, I have found I am usually more eloquent if I just sit and grin.
