The thing is, I've continued buying Lego sets in all that time, to build up my collection. Which means I now have a huge backlog of unsorted pieces. My collection is so large it would be unusable if it weren't sorted. I've got tubs of bricks and buckets of plates sorted by size and color, buckets of sorted slopes, Technic pieces, tiles, modified parts, wheels, people, animals, doors, windows, etc.
And I checked earlier today, to see how many containers of unsorted pieces I have. Six tubs and five buckets! This is gonna take forever. :} And one of the buckets has a temporary label on it saying "HI, I'M FRED" as part of an ongoing plate-sorting operation. Don't worry, it makes sense in context. :}
