I was wearing shorts and a lime green/multicolored plaid shirt.
That's it. That's everything. Aside from info garnered from the posting's subject line (which reveals that this is a 24-year-old male looking for a female), we know the following: He was wearing shorts, and he was wearing a shirt that has multiple colors, though lime green — being one of the aforementioned colors — is the color he's most interested in mentioning. No description of the female he's looking for or what, if any, interaction the two had. For all we know, he has no particular female in mind, and is just throwing out a blind "Holler at your boy" in hopes that one of the show's many female attendees saw him, was interested in him, did not talk to him, and made note of the various colors featured in his shirt, particularly lime green.
What the hell is happening to us? Not that Missed Connections have ever been much more than a scoffed-at means for socially awkward/inept sadsacks to indulge an unlikely fantasy. But at least — even within the limited confines of a Craigslist ad — people used to lay it out there. Whether it be a dude with a penchant for "tiny little pigtails" or a married pair of Nickelback fans looking to get their nasty three-way freak on, nerdy (or creepy, as the case may be) rock fans used to put 'em on the proverbial felt, if you will, saying quite clearly, "This is what I look like, this is what you look like, and this is how I feel." Cloaked in the protective, fuzzy embrace of Internet anonymity as they may have been, they still took a tiny little risk. This guy is basically just pulling a Favre, wagging his proverbial pickle at a hypothetical camera phone and hoping that someone — anyone — will bite (but not literally).
