ACKETY ACK!!! Yes, I do this. In fact, I noticed it not too long ago, when I was cleaning the kitchen counter. Was wiping with my right hand and holding the spray bottle of cleaner with my left. I glanced down, and lo and behold, my trigger finger was pointed out, alongside the nozzle, straight as an arrow.
On a flippin' bottle of Windex, no less!
Guess the gun safety rules morphed into:
1. All bottles of Windex are loaded.
2. Never point your bottle of Windex at anything you don't intend to clean.
3. Keep your finger off the trigger.
4. Know your target and backstop - you don't want to spray Windex on the cat or on the tarantula (Runt, if you're reading this, hubby and me are now the proud owners of a Chilean Rose arachnid fuzzball - she's mega cool!).
