Negotiation Skills

Hey Gugu are you ready to go home? - I asked after spending quite some time on the playground this evening.
No mumma.
5 more minutes?
10! (Both hands and and fingers spaced out for effect).
5, I insisted.
10, she dug in.
6.
10.
Fine, 7, I said closing the deal.
Ok fine.

I'm proud of my negotiation skills!
