Overheard in the car earlier

Was talking to Zet in the car, to which we get the reply "Yes mum, yes mum."

Athena looked puzzled, asked her "Why you call her mum? Call her mummy!"
Zet: Yes mum
A : I say call her mummy......
(we both laughed)

When the conversation went to talking about 'Sir'
A : Call papa, daddy not Sir!

LOL:)
