Beware, houseplants!

Beware, houseplants! I've heard what you're saying
behind my back, they'll be no more playing
tricks on me, trying to put ticks on me
and pursing smirking, greenish lips at me--
"We're only plants, we mean no harm," you cry,
but spend a night or two--or three!--outside,
you'll wish that you'd behaved like civil plants
and, if you had, I'd take you to the dance
tonight, but no! bad houseplants should know it's
time out for plants until further notice.

As important as sunlight and water
is the need for all plants to be proper.
