Many people believe that if a person is smiling and joking then that person is superficial and if a person is serious and always rude then that person has some depth.
.....When KBC part 3 came on tv then many said "what is this Shahrukh Khan is just joking and just wasting time and is not like big B who used to be serious all this is western impact". Without denying the fact that Big B wasn't superficial I would say even if SRK was a little more joking and smiling he was also not superficial. Those who have seen the show very well know how many serious things he spoke in that joking mood.
Now my point is though both of them went on different ways but they both were very serious hosts their own ways.
I am saying this because I have seen many people who look serious but are really superficial.
So its really really wrong to associate depth with seriousness. As our actions are which tell us whether we are superficial or not and not what we pretend to be or what we show others.
