Today was the 2nd day of the tennis camp. The kids there were 5-10 with a few 4.5yo. Yesterday all the older kids got themselves some icy poles with their money. I didn't leave any money with Z&R yesterday. Today, per their request, I gave them $2 each (price of the icy pole; Z gave me an option actually "one golden coin with 2 on it, or two golden coins with 1 on it"). When I picked them up Z still had his money. "I am saving it" he says. R spent all hers... she decided to buy two lollipops for $1 each. One for her and one a friend she made at the camp.
That pretty much describes their personalities.
Zwi also won the trophy for the best player in their division.
