I try to be as honest as possible as often as possible; I like to joke around and not take things too seriously - despite how this paragraph is coming off - but I wouldn't mind meeting someone willing to get serious. Cool? Cool.
Oh, and when I recently asked a date how I was different in person compared to my profile, she said (and keep in mind, this person actually wanted to meet me), "I thought you'd be...[uncomfortably long pause]...meaner." So you've got that to look forward to.
