water the plant with your tears

cry on the plant, to water it

You suddenly feel very concerned for the only other living being in your near vicinity, and figure you should try to nourish it somehow.

You decide this is the best thing to do right now, you have no way to access the rainwater outside to use, and you can't recall if the little guy ever even been watered. You don't know much about plants.
