When you try talking to a friend who seemingly ignores you for days at a time and gives no attention back, and overall acts like they don't want to be your friend anymore. Just like giving
water to a dead plant, the plant
will never grow again or give anything back. Hence the name, watering a dead plant.
girl 1:

girl 2:
ditch him, you shouldn't be
friends with someone who doesn't match your energy
