There are times not to flirt. When you're sick. When you're with children. When you're on the witness stand.
You've got a big, big problem if you get caught up in what people say. If you're gonna live for what people say, you might as well lay down and forget it. Because it doesn't work that way.
I shall have less cause to regret the carrying my intended purpose into effect, foreseeing that you may immediately fill with advantage, the vacancy which will presently happen.
