When I was a teenager, I generally came across as a happy person.
But one high school student who I knew didn't like me because he was jealous of me. He believed that my quality of life was better than his was at the time. And I think that he thought that I was a happier person in life than him.
Little did he know that, back then, I was dealing with severe depression much of the time. My life wasn't so rosy back then.
Just because someone appears to be happy, like I usually did back then, doesn't mean that they actually are. Just because a person appears to have a life that's good doesn't mean it actually is. You never really know what it's like to be someone else. You never know what's going through somebody else's mind.
If he had known what I was going through back then, maybe he wouldn't have been so jealous.
