@selectmytutor,
You call yourself "Select My Tutor" but you don't seem to have a clue how English works. Your mistake is to act like you do, you give false and misleading information all the time to people learning to speak English. It makes a mockery of this site's name.
Instead of giving out wrong advice you need to take some English lessons yourself, and more importantly you should stop giving advice on grammar threads. You don't know what you're talking about, most, if not all, of your advice is wrong.
