Excellent English

I am writing this post as a F.I.R that is,i am writing what I witnessed at a shop.I was waiting in the queue to pay for the soft drinks i had bought when a little girl,barely 4 years old spoke to her father.
“Please,if you are my father,buy me this drink”,pointing to Pepsi and then “Please,I beg of you,buy me that drink”.My god.Speaking like this at a tender age of 4 or 5!Amazing.
And there are some who think that they know to speak proper English,what we call “peter” but au contraire they know only local English(Butler English).If a small child can speak in that way,why cant we all.All it needs is practicing.
