Where's Lucy?

Does anyone know anyone like this? For the past four days the house has been in shambles - beer bottles, laundry, and dishes everywhere. So when the person who is responsible for the mess decides to do some cleaning he gets sidetracked midstream, leaving everything only partially finished - and this I've found is his regular M.O.

For instance, on the porch prior to the "clean-up" there were three beer bottles, a pair of shoes, and a full glass of wine complete with drowned bugs. After the clean-up - a pair of shoes and a full glass of wine (bugs still intact). Why wouldn't you, while you're at it, grab your shoes and the glass of wine? Like why would you move on to another task prior to finishing the one that's only going to take 30 seconds to do anyway? Do you forget? Or, is it that you just can't bring yourself to see it completed because...oh, I don't know...you are afraid of success?

If anyone has any psychological insight, maybe because you're this way, I'd appreciate it.
