Just realized I haven't posted anything in a while here. You know why? Because I was sorting my LEGO blocks. Yup. Took me two days. You know why I did it? Because I wanted to find that 'one piece.' I had a piece that I used for something a few months back, that I was pretty sure was in my 'LEGO box.' I am now in a position to tell you with 100% authority that it is not in that box.
How you ask? Because I sorted the whole box. Downside: I don't have that piece anymore. Upside: I can now tell you where any given LEGO piece I own is sorted at.
It's a little frightening.
