you need not worry about your skill English... infact adding a friend is simple , but to reply his ? is a bit confusing ... who r u ? so for this you need to search some answers or some quotes online if you don't have a skill English...
facebook is gonna shutdown on 15 march its announced
No, it's not... Facebook is a huge money maker that's growing at an insane rate, the notion that it would shut down is simply absurd. It's widely been covered that this is nothing more than a silly, albeit, well marketed rumor.
If you want to make friends from facebook you can easily add friends along with nice quotes and status. There are lots of friendlier people on facebook and I believe they're not hard to befriend and help you with your English problem.
