Yes Zubair, I'm like a million percent sure you are not an English teacher. Now I'm going to publicly ask you to do a few things:
1) Don't say you are an English teacher
2) Stop correcting people's English entries:
You are doing more harm than good and many of these people are learning English for professional purposes. You are possibly ruining someone's career. Also, languages are frustrating and hard already. Don't make it worse.
3) Don't give yourself a C2 or fluency rating on your profile. I would say your English is A1 at best.
4) Don't tell people lies that you are a doctor like you did yesterday, and that you are building a hospital in Dubai, that you are meeting with the Pakistani president and that you are Syrian doctor.
If you do anymore of the above, I swear to God I will haunt you like a ghost on this site. You do not mess with people, and I have plenty of time and resources to chase you down.
Sincerely,
Lady
