My real name is Jesse. Nothing more, nothing less, and not short for anything. (I get mispellings and misconceptions all the time: Jessie, Jessi, Jessy, Jessee, Jessilyn, Jessica, etc. Even people who have known me for YEARS still spell it wrong. I hate it.) Just Jesse. I like it that way. It's a good name. I'm pretty sure it means something like "God is great," or "gift of God." =)
I was really defensive of the masculine spelling when I was little, though. I even punched a kid who said it was stupid for a girl to have the name Jesse; thankfully, I mellowed out, but it's still annoying for people to always assume that I've mispelt my own name. ("It says Jesse here. That's short for Jessica, right? Or is the 'i' missing?" is obnoxious about the tenth time you hear it.)
But, yeah, I love my name~
