I littered at a beach party and didn't clean up
Why didn't you clean it up?
I want to change the world starting with me.
A lot of people use the beach and its expected that everyone picks up after themselves. You need to do your part to make the world a better place for others.
I don't want to care about everyone else since I only care about myself.
It's pretty selfish to care only about yourself. If you're using a beach, it's your duty to do your part. Think about it and try to change your attitude.
