[Len Case]

No bad childhood memories tied to "Lens"... as a child I was always "Lenny" or sometimes even "Lennie"--in fact I was still getting reminders from my dentist for "Lenny Case" several years into my marriage, much to the amusement of my wife.

As an adult when telling people my name, I often got "Lynn" so I started telling them that my name was "Leonard" and then letting it switch to "Len" naturally.
