A conservative Iranian newspaper has accused President Mahmoud Ahmadinejad of indecency and a violation of the Shari'a after he kissed the hand of his former schoolteacher. At the moment the controversial gesture took place, the teacher was wearing gloves (BBC).
This just goes to show the extent to which Iran's conservative establishment is willing to go to intrude into the everyday lives of Iranians, despite the fact that this sort of behaviour exposes them -- and Iran -- to international ridicule. So the man showed respect and affection towards his childhood teacher. It is the newspaper that is being indecent.
