KEEP LIQUIDS, POWDERS, ETC. - IN THEIR ORIGINAL CONTAINERS!!!!
So many of us are accustomed to something being in a certain container, that we just assume that the "usual thing" will be in it.
The reason for this post - and - in this case - it's only inconvenient - not life threatening -
DH had put hydraulic fluid into an oil container. He thought he was changing the oil in the garden tractor. He had labeled the oil container - but was in a hurry and overlooked the label. So NOW he has to do the whole thing over.
(I was very proud of me - I kept most of my comments to myself!)
