Never, you repeatedly greeting them " Eid Mubarak " and you are also expecting the same from them. Neither you nor them deserve it. It was never a congratulation, rather it is a reward. Why would you be rewarded and why would He be helpful if you were never were grateful. The environment just become rotten, the ideals have become putrefied and you friends had died. It is the reward for those who strived hard, not for those who practised idly.
" Eid ul Fitr as described in the Qunut is a source of honour and dignity. " - Ayatollah Sayyid Ali Khamenei.
