When we enquired as to why people did not care about showing themselves we were told something quite unexpected. Apparently people in Iran will show off their new nose job as soon as they are discharged from hospital for as long as possible. It is a status thing!
A typical nose job costs 3000 to 4000$. That is a huge amount of money here so people display their wealth proudly. It is not uncommon to fake the surgery either and just wear the band aids.
