Tears

Yes, she is the one whom we cry on her shoulder, she is the one who enjoys our tears of joy and she is the one who cries when she feels our sadness.
That's true, mothers mean tears, tears in their different kinds, even if your mother got the tiniest wound cut, you would feel self-irritable, no one can imagine a beautiful day without her presence, and no one will ever remember a happy memory without her soul in it :')
Her entity fills our lives with every little meaning of the reason why we wake up in the morning.
