For us, this game would be easy, since all this stuff took place in about three different bars.
This is like the first half of the book Gone Girl (no spoilers!), except it's videogames and electronics that are missing instead of a woman. Pretty cool of Kelsi to take care of all those photos. Also, who still has printed out photos? Or, did she just give Kelsi the sim card from one of their phones? Regardless of the logistics of this game actually being carried out, we're keeping it in mind for our own future breakups. And don't worry about this broken-hearted girl. With penmanship like that, she can't go anywhere but up.
