Honestly, is there a MORE LAME, LYING excuse out there? Especially if you've texted the person before, so you have their contact info right there in the messaging program so you just hit "reply". I swear, "I didn't get your text" must be RIGHT UP THERE with "I've been hacked!" for the Technologically Clueless Liar Attempting To Place Blame Elsewhere.
Except, of course, when the protester of innocence in question is Mojo, a blameless and saintlike creature who is also extremely technologically savvy. Not quite enough to be a true geek, but close enough that she gets most of the jokes. As Mojo continually likes to point out to you lesser beings, she's been online back when it was all done via Unix commands, typed out in knee-deep snow uphill both ways. Yadda yadda yadda, someone shut her up.
