Carry a baby in a stroller and walk around the city, you will find:

• Young-aged men, middle-aged men and old-aged men are very considerate to parents with a baby and will give way to you.
• Some old-aged women are considerate to parents, some will give way.
• Middle-aged women, especially mothers, appreciate the baby most, often very considerate and find interest in the baby.

Young-aged women... here is the interesting group:

• Young-aged women, who have experienced or helped in motherhood, are considerate and interested in babies
• Young-aged women, especially attractive and in the early twenties, will bump into you, fight you for the doors and race you to the store registers...
  
  Young-aged women... Masters of the universe.
