“We cry because we carry on a big mountain in our back
We smile because we thought that what we had is enough
We laugh to express our happiness”
Some people are very expressive and choose to show their emotion but some also laugh to cover their sadness.
After all we can choose to express or to hide our emotions, or we can choose to be plain, walk the talk in the same tone, stare in the same rhyme so nobody knows what’s actually happened.
Those choice made by human for many proposes, some chose to express to get sympathy, some just be theirselves, some keep silent because that’s the way they really are but some are trying to be plain to protect theirselves
