So how did it happen?
On February the 18th, nearing midnight, Lara and Eric were playing Dance Dance Revolution in the basement of the house they were sitting. Lara's favourite (and Eric's least-favourite) routine, "Never Ending Story" had just ended.
"I'm going to play this song until I get an A-star rating!" exclaimed Lara.
"I'm going to use the bathroom... upstairs." Eric said as he began his ascent.
"Poor guy..." thought Lara, "That pizza we had for dinner must not be sitting well."
Rushing into the bedroom they shared, Eric put his plan into motion, pausing every few seconds to verify that the steady "thud thud thud" noise was coming from Lara's feet on the dance pad and not on the stairs. At last, all was ready and Eric returned downstairs for at least another 57 rounds of DDR.
Finally it was time for bed. Eric followed close behind Lara as she headed upward. Nonchalantly, he headed to the washroom as Lara entered the bedroom.
"Why are the blinds rolled up?" Lara asked, for she has an acute phobia about people peeking into second floor windows (because, apparently, it is what she herself does).
"I dunno." Eric said from the washroom, observing in the mirror his instant wince - why did he say that?
"What do you mean you don't know?" Lara countered, "If I didn't do it, and you didn't do it..." she trailed off, letting the logic sink into Eric's thick skull.
"I was looking at something outside..." Eric could hear Lara moving towards the naked window, so he slid silently into the room.
"Oh." Lara replied, and began unrolling the blind to reveal...
Post-it notes? Why were post-it notes stuck haphazardly over the blind? She looked at Eric, but he just had a silly grin on his face.
She took a half step back, seeing the true form the post-its held...
