I was named after Bret Maverick (TV Western 50/60s), the name has lessoned in use over time and I find more girl Brett's then I do male Bret's.
I have been called and written to as:
Bret
Brett
Bart
Brent
Bert
Which bug the time out of me when I was younger. But now that I am more mature (older) I am just glad I am around to respond to whatever I am called. There is an old saying call me what you want, just don't call me late for dinner. :)
