At one time in my life, I thought I had a handle  on the meaning of 
the word " service: "The act of doing things for other people."

Then I heard the terms:
Internal Revenue Service
Postal Service
Civil Service
Service Stations
Customer Service
City/County Public Service
Road Service

And I became confused about the word "service." This is not what I 
thought "service" meant.

Then one day, I overheard two farmers talking, and  one of them 
mentioned that he was having a bull  SERVICE a few of his cows. 
SHAZAM!! It all came
into perspective. Now I understand what all those  "service" agencies 
are doing to us...
