جزاك الله خيرا مستر ابو بيشو هذا رأى مدرس بريطانى فى المنتدى الذى طرحت فيه السؤال :
It depends on who you ask. Very conservative textbooks insist on I. Less conservative guides and actual usage allow me. So you might say that both are correct. Note, however, that in many cases people use neither one. They say, "I am the one who broke the vase".
هل حضرتك مع اختيار me ام I?
