Generally children get their inheritance from parents.The natural qualities of parents but not the qualities parents have developed later in their lifes due to some situation changes or circumstances.
Indira was a happy girl in her childhood.Neither she was a hitler nor she is short tempered.Infact she had good interest in music and dance.she loves kulfi and happily plays with her father in childhood.
So the natural qualities of indira are good smile,interest in music and dance etc etc.
These are the qualities the small Indu must have if she is a xerox copy of her mother.Her mom changed due to circumstances.this change in her mom was a forced one not a natural one.But when Rishi came into her life there are situations where is smiles,laughed,danced and did everything.So Indira's hitler giri was not her by birth quality which can be inherited to Indu.
And cv's for some story sake they are showing such things but logically whatever they are showing are not but just bloopers.Hitler Didi was a real story of a girl in the beginning.The feel was like that.Later ILLA BEDI killed that feel with her non ending bloopers and gimmiks.
I wonder why a 8 yr girl is wearing suits like elders that too collar model types.Why can't her mom and dad make her wear frocks like her age girls wear.No wear a 8 year girl will go to a shop on her own and buy such clothes.
Many times its getting proved that daily soaps dnt have logics but only gimmiks and magics and unfortunately HD is one among those daily soaps.
