Thrice times

Nidhi is plucking blossoms from a tree in the garden.

4yo: Here, I got one for you

Me: Thank you

4yo: And I got one for myself and one for daddy

Me: That's good

After some time

4yo: Can I pluck some more

Me:Sure, you can get 2 for each of us. So how many will that be?

4yo: 6

Me: And if you get 3 for each of us, how many will that be (thinking this will be difficult)

4yo: 9

Me (impressed): And if you get 4 for each of us, then how many will that be? (certain that this will stump her)

4yo (without hesitation): 12

I don't know how she does it!
