Usually when I just came to a company or a place where I could have
some leisure time or was relaxing for chatting with people for a while,
I would be very happy to call the nicknames of my colleagues or friends.
Actually I made the nicknames for them, not just calling it in front of them.
Took some persons for instance,
I called one, the mayor, and the other, the brother, and another, the grandpa.
Sometimes it was fun for calling the nicknames at the working places.
Do you have any nicknames for your background?
