Yeah I think we can exchange in free time

كان فعل ماضي ناقص، يرفغ المبتدأ (الاسم الاول بالضم) وينصب الخبر (الثاني بالفتح) مثال: كان الأبُ لطيفاً، كانت (هي) وافقةً على الشرفة، كنت (أنا) خائفاً، كن (أنت) قوياً وشجاعاً أما اذا كان فعل فلا يتغير شيئ: كانت (هي) تقف على الشرفة، كنت آكل عندما اتصلت بي

HOLD IT !!!!!!!! Now if you're talking to a Lebanese (and maybe Palestinian) that would mean exactly the opposite, unlike Egyptians or Syrians we use ma for "don't" so "ma tistihe" means "Don't be shy", and if you're talking about someone else who's shameless or rude it becomes: ma btistihe (she doesn't get shy, or in another context she's shameless)

correction of my "introduction"

Hey, how's it going? I'm Richard and I live in the State Baden-Wuerttemberg, which is located in the South of Germany. Currently, I'm a student who learns foreign languages as well. (here do you mean student of some specialty ex:biology that is learning languages as well?)
I love learning new languages and that's why I wanna (you say it wanna but shall write it want to) help others <strike>to</strike> learn my native language German. Besides <strike>of</strike> German I speak English, a bit of Russian and a bit of Spanish. I had the opportunity to teach private several people the German language (to  privately teach German language to several people). These include<strike>s</strike> Spanish-speaking, Russian-speaking and Arabic-speaking people.

My focus is the colloquial language, vocabulary, pronounciation, phrases and idioms. Furthermore, I'm gonna (going to, "although you pronounce it gonna:-)    explain <font style="background-color: yellow;">to</font> you (or teach you) complicated grammar rules in an easy way (with examples), so you can understand it. And I'm gonna (going to ) show you the real spoken German which is used in daily conversations.
Please let me know if you have any further questions. I will answer them all :)
