Story of a Beautiful Girl

They were enjoying the fabulous dusk.Really they were made for each other couple. He was well built and handsome too.Sitting with her dearest person she, heroine of this story, felt as if she is in heaven. She is the most beautiful lady that i had ever seen. So dazzling. Ruby lips,dusky eyelids, and rosy cheeks made her the most beautiful woman in the world.In soft but strong romantic voice he said to her "You are as soft as hydrated magnesium silicate".(:-D) "WHAT? She roared in angry. Yes friends, hydrated magnesium silicate is the softest mineral known. Its nothing but 'talc', the common ingredient of talcum powder. In talc , magnesium is found sandwiched between two silicate layers. Put some talcum powder in water. Is it soluble? No. Moreover they resist moisture too.Due to these reasons they are used widely in all cosmetics. Is talc harmful? Ok lets come back to our story. Days passed and in the course of time their (lover's )bond enthalpy increased. In a fine evening she didnt felt so fine. She was so tired and very weak. Her endless journeys to the hospital and eternity started from there onwards. Doctors confirmed that she is a victim of severe cancer. Decline of her majestic life! Her rosy cheeks became pale and dark,they reflected a melancholic mood. Hero of our story was just a 'fair weather friend'. He left her and searched for other beautiful girls. Through the windows of the hospital she watched another fabulous dusk. "What's the reason for my disease?" she engaged in a deep thought. She recollected that funny words " you are as soft as hydrated magnesium silicate" Talc! She got the answer. Talc was the assassinator of her royal life. Asbestos like fibre present in talc is a potent carcinogen. So better avoid talcum powder use.
