"Yeah I know Madu, We are just having banter between friends. That reminds me, Where is your son Adiratha? Isn't he taking too long to come back from taking a bath?"
Vaibhav stopped messing around once his wife entered the main hall, He nearly forgot he did not come here just to have fun, He came here to fulfil the promise they made as kids.
And yet he can't help it. The innocent fun, the banter, fights over sweets everything comes over once again when he meets his friend, They both belonged to different Varna.
He is Vaishya (Business caste), While Adiratha is Shudra (Servant caste) and yet they never felt alien to be with him, This does not affect their friendship even a bit.
This is a reason why even knowing what will society will say, He was not afraid and came here to fulfil their promise.
