...your mom starts using the nickname on everything.

My legal first name is five letters and frequently (as in "always" outside my family) mispronounced. Searching it straight also brings up a website I don't want my employer or my parents to see. So I went with a three letter nickname. Easy to pronounce, works great, a romance author has the same name. My elderly mother likes it so much she now uses it on everything. The point was to keep work and non-work life separate--and she's blurring the lines. Oh well, it could be worse.

My sister's nephew (her brother-in-law's son) is a rookie driver in NASCAR. Every track has a computerized simulation and he drives the sim every week for practice, even if he's not scheduled to drive in the race. All the drivers do these sims. I have no idea how much these sims cost to produce, or how often they're revised.
