We were driving by some farms yesterday, and saw a bunch of cows. DS5 wanted to know how the farmers got the milk from the cows. I gave him some basics. He asked about when the cows start giving milk, and when they stop. I told him what I knew. He said, "Mom, I think the cows are slaves." He said he hoped they all escaped soon. I told him I thought the beef cattle were a bit worse off than the dairy cows...
