You are right Rajnish ji but you may sometime agree that we all behave differently with different people according to various factors such as our relationship, post/position/rank, age/peer group, gender, economic/social status, physical appearance/ability, behavioral pattern, intellectualism/knowledge, residential/operational zone and may be more. To know everything about a person on this virtual forum seems difficult but in case some of the above criterion are known to us our addressing to each other will definitely improve and I think that makes the difference.Secondly, respect works on Newtons third law of motion.Give respect & take it back (some time with interest). What i have experienced that even in our offices/workplaces we address senior/older people by adding JI to their name even though they may be our subordinates/sahayaks and that enhances interpersonal relationship & improves working environment.
So the age seniority is a very significant criteria to decide initial addressing. Further in case a senior/aged person does not behave according to his age/seniority then he needs to be held responsible for unpleasant consequences if any. In my opinion the above applies here and everywhere. The idea is to exchange/share our knowledge/experience/culture in respectable, humorous and harmonious atmosphere.
With Thanks.
