What Do You Mean When You Say …
The English language has plenty of words that have two meanings. It also depends on the generation to which you belong. The juxtaposition of words can also lead to confusion, just like this message from grandpa in response to greetings from a grandson on the grandparents’ 51st anniversary.
You will never know whether grandpa willfully misunderstood what was written or just took the words literally. And you would not want to ask or correct them. The old geezer can be wily as a fox and could be pulling your leg.
