radhaji made use of word AABHAR meaning thanking someone.
this word is generally not used frequently but only to the respectful people or people having high-profile,status or referring to god.
and this word is not adopted by many other serials and hence makes it very different n special.
radhaji had earlied thanked AABHAR to ganapati bappa and now did AABHAR to sikki for offering 1st rishbala wedding card to bappa's feet.
though sikki's intention was for his own benefit,I appreciate radhaji did AABHAR to sikki without any hesitation as her only concern is rishbala n their happiness.
on the other hand,radhaji's son rishabh has the most twisted vocabulary.
