Many years ago, while my daughter was a toddler, she came running to me exclaiming "Papa ! Papa ! I saw a papa deer and he was hugging the mama deer !"
A few years later when she's in grade 3...I'm driving her home from school and I hear from the back seat, "Oh man ! You're not going to believe what I just saw. I saw one cow and it was on top of another cow !"
