Innocence

After QMP, I have ventured to teach Maths to my kid.

'How much is the bill, Pavan?'

'Rs 110.'

'110? How? Whats the breakup?'

'Rs, 57 for the sandwich and Rs 41 for the coffee.'

'57 + 41 = 110?'

'No. Total is 98! They are charging 12 bucks extra! This is cheating! Shall I go and tell them?'

'No, darling. The 12 bucks is for Tax.'

'What is Tax?'

As usual, I am dumbfounded at his question. As usual, he helps me out.

'Oh, I know! Tax is the sauce!'
