What you see, is not always what you really see.
People have their own “thing” that does not have to be publicized.
They might laugh, but cry behind.
They might sad, but happy behind.
They might look bad, but nice behind.
There might be something behind the curtain that we do not know. Do not judge others easily, until you can prove the judgement.
Remember, everyone will be judged upon their judgement.
