First, the note!
Passive aggressive perfection!
And the aftermath... Ah! Turns out that the note wasn't in reference to a kiddie pool gainfully used by toddlers to keep cool during this recent Fall Heatwave of 2013™ ... it appears that the kiddie pool in question may have been keeping the brews cool during a recent rooftop rager...
Regardless. Someone sort of half-dumped the pool in question. No word on where the mosquitos are.
