Well if you have meaningful convosations and answer back as if the plants are repling that might be an issue. I personally look at it like this ..Im thier god I hold thier lives in my hands from the day they are born til the day I hack them down and smoke thier dry lifeless bodies and enjoy the smell of thier souls.I yell at them "Grow you mother fuckers or there will be hell to pay. I am your master and I command huge sugary colas or else you will feel my wrath!!"...Seeems to work never any back talk and yields seem to be decent maybe thats just me though.Happy trees and bushes...happy I say!!!
