If Suman had slapped her at the right times,presently Deepa wouldn't have been required to do it. Facing and overcoming hard times doesn't justify the way she has brought up and given values to Pari.She encouraged her and stood by and watched whenever she ranted against Sonakshi who is her elder sister. Pari spoke ill of Sonakshi behind her back and instead of putting her in her place,Suman scolded Pulkit who was speaking the truth.Sonakshi has literally brought her up for the better part of her life and Pari should be respecting her as equal to her parent.Suman is responsible for Pari being beyond redemption now.
