Input: Text: (yesterday, not today)

life has been stupidly hectic for my partner and me recently and we've had no time to ourselves. for a while, we'd been planning to keep yesterday free to simply spend some quality time together and chill. at the risk of getting a little personal, we'd not had much time for *ahem* sexy times *ahem* recently and so we had begun referring to our upcoming day together as 'marathon sex day'. just before going to bed at ~2:00am yesterday morning, i scribbled on the magnetic doodle board that lives on the bathroom door 'happy marathon sex day!' to give her a giggle when she found it. the next thing i know, it's sixteen hours later and i stumble to the bathroom to see this: http://i.imgur.com/std1rcy.jpg let's just say she was less than impressed and about to head off to collect her children, marking the end of the marathon sex day that never was =/
