I just vacuumed my room.
After I emptied the vacuum cleaner into the bin and put it away, I came back into my room to found — right in the middle of my carpet — a little pile of grey dust with a nail sitting on top. Where the little pile of dust with the nail sitting on top came from I have no idea, but I’d just vacuumed and here was this infuriating little pile of vaccuming needing doing.
So I whipped out the dust buster to bust the dust, and it was full and wouldn’t suck. So I had to empty two vacuum cleaner bags and vacuum twice, and the end result is a nice clean carpet. So I guess it was worth it.
