In the early years we learn what words mean. Based upon that early education I learned that the word "service" meant “doing things for other people," “helping,” and things like that.
Then I began thinking about these uses of the word “service”:The Internal Revenue Service
The U.S. Postal Service
I became confused about "service." These things do not reflect what I thought “service" meant.
The other day I overheard two farmers talking, and one of them said he had hired a bull to "service " a few of his cows.At that moment it all became clear.
