have you secretly have taken care of someones plant?
I have in my english class there is a poor pathetic looking mini rose with just barely any leaves on it. One day i walked into class and saw the rose drooping really bad so i accidentally dropped my water bottle in the pot. The next day the plant perked up, WHOOOO. So i may have helped that plant survive a bit longer. Maybe next time i will put some fertilizer into the water bottle and accidentally drop the bottle in pot again when it starts looking droopy.
