grammargirl, 
Sunday morning language meltdown:
I'm writing an example sentence about buying flowers, and suddenly, "nursery" seems like a weird word to me.
Do we really buy flowers at a "nursery"? It's also where we keep babies.
Sure, we nurture both flowers and babies, but will people outside the U.S. know that a nursery is where we buy flowers???
Maybe I should say "hardware store" instead.
OMG, why do we buy flowers at a HARDWARE STORE...
<runs away screaming>
