Knitting Frustration Defined

I've spent the last 3 days knitting on and off, I'm making a summer wrap with a variety of yarn and it's very nearly finished. Imagine my frustration last night when I have 1 row plus the bind off to go and I glance at the clock to realise it is midnight! I now have to spend the day distracted by the project I know I'll complete tonight. Why can't I be at home crafting? Why?
