In a land like ours(India), respecting your elders, goes without saying. It is grilled into us from childhood but how important is it to display the same?
Is it true that you value your elders only if you address them with phrases such as "bhaiya/anna","didi/akka", suffixed to their names or by falling at their feet every time you meet them? I am not saying that one MUST NOT do such stuff. Infact I have observed over time that most(not all) elders find a certain pleasure when you ask for their blessings and fall at their feet(I don't lose anything by giving them that happiness and so I do so, when required i.e. on occassions). Yet, I feel that respect is something one must feel from within towards the other irrespective of age, relationship and displaying respect is NOT MANDATORY. In other words, if you don't fall at your elder's feet or address them in a certain manner it does not mean that you DISRESPECT them or that you are ILL MANNERED(some people strongly think otherwise).
I think the same applies to PDA!
Follow your heart and do what you believe in. Simply suit yourself!
Non-related Stuff: I finally visited the Race Course and it was a beautiful sight to see those majestic, handsome horses run the last lap in reality as against watching the same on the idiot box. But for the bad crowd and sadly maintained Turf Club, I'd sure love to visit the place more often!
