- you mean if I knew of him. watching TV
- yes, did you know him?
- if I knew of him.
- ?!
- I did not know him. I knew of him.

I burst into laughter

-?
- you know, the other day, my mum was asking me if you understood Persian. I said yes and she asked me if I talked to you in Persian and I said no, why, she asked and I replied cause Chris speaks English so well and makes fun of my grammar mistakes, still laughing
- yes and I am not giving you the chance to laugh at my grammar mistakes in Persian. back to watching TV
- well, it would be ok, cause Persian is not your second language.
- No, it is not, well, it is actually my fourth language.
