Also, a second thought: like, unless it's super formal conversation related to work, I don't ever give people my last name in greetings (and I've yet to see any social conventions in game that dictates that characters universally give their full name as an expectation, either). Hell, most of the time it's my nickname, which people don't even know what it stands for half the time, or guess wrong. Several of my characters give nicknames or aliases, and it was never a big deal icly. So, I mean, that could also be used as a means of deflection, too.
