If you don't want anyone to criticize you about anything, maybe you should go live in a cave. Pride should come from acknowledging your weaknesses and committing on improving them; and not from hiding your weaknesses and running away from the truth.

Also, if TIA wants to call itself and "International Airport" then it needs to be willing to hear concerns of international travelers and meet international airport standards. Otherwise change its status/name to a regional airport and let someone else (maybe lumbini, bhairabha) truly host an international airport.
