She wasn't there when her son married the love of his life.
She wasn't there when her son needed her the most, the moment his wife battling with pain, with death.
She wasn't there when her son first cuddle his bundle of joy.
She wasn't there to witness every greatest moments her son were having,
her son dutifully remembering her and all her motherly rejection along her forever absence.
And for that, I shed my tears.
