Why do Pakistani people speak English mixed with Urdu so much?

Re: Why do Pakistani people speak English mixed with Urdu so much?

I think if you are bilingual its natural for words of the other language to creep in during conversation.
I have words from english as well as arabic creeping in while conversing. At times even complete proverbs in arabic. Its not done on purpose. It just happens unintentionally. In fact its a hinderance because at times I may use urdu/arabic words unintentionally infront of an audience who understands neither.
