This one's for Dad

Here’s an overheard conversation between a father and a son sitting late evening at Girgaum Chowpatty. The son was collecting the sand, trying to make a sand castle.
Son: Pappa, bada ghar banau yaa chota?
Father (looks at his son trying so hard to collect the sand): Beta, chota ghar banaa.
Son (looks at his father, then looks at the sand): Nahi, aapko bada ghar accha lagta hai naa. Main bada ghar banaunga.
