I too get impatient when confronted with incomprehensible cluelessness. I know that's a character flaw of mine, but it doesn't seem to change my reaction.
Recently, I was asked where you "plug in" an emergency generator. No, not to feed power to the house mains, but where you plug it in to make it run.
Then, when I explained that there is a gasoline engine that turns the electrical generator, I was asked whether you need to pull a cord to start them? As opposed to just turning a key? Well, it depends whether the generator also requires a battery, and whether that battery is kept charged for months or maybe years between use. The correlation between starting an engine by turning a key, and having to have a battery, was apparently a new revelation.
So, am I surprised that someone can't figure out how to measure the volume of a liquid? That seems way more complicated to me!
This is such a simple mistake it almost beggars belief. It raises questions about the quality of the educational system amongst other things. I also wonder exactly how the vet showed her to fill the syringe. Like Zeeglen I wonder what job she does, and how she got it...... I also wonder whether you will get an apology ever, because you almost certainly did save the dog's life. I think "Cruella" is being a bit harsh, "Stupida" would be more fitting.....
@betajet: I once had a cat with diabetes, and I used the standard 1.0 mL syringes (or more likely 0.3 mL -- it's been a while) with a typical dose less than 0.1 mL IIRC.
Hmmm, now I come to think that 1 liter is 1000ml, I can't believe that the syringe holds 100ml -- maybe it's 10ml or even 1ml (I doubt that "Cruella" will let me look) -- when I come to think about it -- insteal of 18uml, maybe she just said "18 of the divisions on this syringe" -- or maybe she did say "18ml" and I took her at her word without thinking it out -- but she definately meant 18 divisions on the syringe.
I once had a cat with diabetes, and I used the standard 1.0 mL syringes (or more likely 0.3 mL -- it's been a while) with a typical dose less than 0.1 mL IIRC. So when I read 18 mL I immediately thought your friend was about to kill her dog with 10X or 100X the prescribed dose. Kind of like confusing 20% blood alcohol content with 0.20%.
"How sharper than an insulin needle is the sting of a misplaced decimal point."
I'm thinking that "Cruella" simply couldn't wrap her brain around vizualizing the syringe being "upside down" (i.e., pointing upwards) -- by comparison, I think I have relatively good spatial and 3D visualizatiobn skills. Do you think this comes with being an engineer (or vice versa), or is it just a case of "some folks have it, and others don't"?
