Wow, you are a lecturer. That's really good. I know it can be difficult especially when you have 50 students in front of you! You can speak farsi fluently? Including pronouncing difficult words like qhermez?? I can never get this pronounciation right. letters such as gha, kha, ayn, ra is difficult.
Speaking English is easy but yes the grammar can be difficult and confusing.
