1.about sb/sth درباره کسی/چیزی
Ex: this text is about myself این متن درباره خودم است (lit. this text about myself is)
-----------------
2. I love Rafe من راف را دوست دارم (lit. I Rafe [ra] I like)
in Persian it is necessary to to use object marker (را) after an object, regardless of whether the object is someone or something, although the above sentence can paraphrased in way that using "را" wouldn't be necessary. like this:
I am in love with Rafe من عاشقِ راف هستم (lit. I lover [e] Rafe I am)
-----------------
3. age can be expressed this way
Ex: I am 20 years old من بیست سال دارم (lit. I twenty year I have)
colloquial way: بیست سالمه (lit. twenty I am)
if you can't read Persian alphabet, let me know and I'll transliterate the parts written in Persian script for you
