The art of negotiation

I am downstairs when Nidhi wakes up in the morning and calls for me.

Me (entering her bedroom): Time to wake up!

4yo: Sleep with me for some time. Sleep with me for 3 minutes.

Me (hoping to negotiate): 1 minute

4yo: No, 3 minutes. (Pause). Because you said 1 minute, I am going to make it 4 minutes.

You can't win.
