Two friends Billooo & Tillooo went to school for appearing in English exam (7th standard). They had crammed an essay of "MY BEST FRIEND". But unfortunately, in the question-paper it was written ...... write an essay on "MY FATHER†in just 30-45 words . So Billooo was utterly confused & nervous ...what to do!!! Tillooo gave an idea! Just write the essay My best friend & just keep on replacing the word friend with the father. So this was how Billooo & Tillooo wrote the essay "MY FATHER".
