OK, I admit it.....I have accidentally taken a sip out of my dirty paint water. Eeegads!! And I'm still alive to tell you about it. In the groove of some serious painting mojo, my hand instinctively reached for the glass and took it to my lips. In that instant of recognition, I spit it back out, no harm done.
I had to take measures to ensure this would not be repeated. My dirty paint water glass is now appropriately labeled with the big red circle with a slash through it, labeled "Drink Not". It will always sit on my right. The mug or glass that I should rightfully drink from are always positioned on my left.
Sometimes, mistakes make us better.
