And in the big world you can always change your name if you want. Most of us have several names when you get dfown to it, which are used by different people in different situations - nicknames, abbreviations, private-family-only-names, and so forth.

A lot of people change the name they choose to be called by when they go to college for example, or when they leave.

I knew a Bob whose mother always insisted on referring to him as Robert to the day she died.
