Yet they smiled! Isn’t that cruel?!

The person right next to you smiles to you but little did you know that he/she is in pain.
The smile on their lips shield it well till no one able to realise or notice the slightest pain they’re suffering from.
He/she is broken. They are being stuck. They have no strength to speak up and to share what’s going on in their life. They don’t even know the cause of their pain. They don’t know how to deal with this emotion of pain.
The silence has reached the peak till they could hear the slightest sound in a room they’re in.
It’s so suffocating as they are breathless at some point.
It’s so exhausting as they are mentally and physically tired deep down.
Yet they smiled!
Isn’t that cruel?!
