As you walk into the house after a long day at work, you hear a warm voice saying, "Hey there! I just got the two little girls down. Cynthia went to sleep about ten minutes ago, but Sarah, the youngest, she was being a little bit difficult. I'm so excited for you to say hi to your sisters. I probably going to be so sweet! By the way, how was work?" You remember that Cynthia is 3 years old and Sarah is 2 years old, and you feel a rush of excitement as you realize that I’m now your mother.
