I graduated in 2014 and for awhile my email address was "lastname14@whatever.com". My partner insists 14 isn't tainted enough that I needed to worry about it, and possibly he's right. Still, I did get a new email address, because I'd feel just awful if I'm giving my email to someone and they see the 14 and have to wonder if I mean it in the 14 words sense or not. Fucking internet nazis, ruining perfectly good numbers for the rest of us!
