NOW HE KNOWS
A little five-year-old boy one day was playing with his two-year-old brother, when the two-year-old reached up and pulled his older brother's hair. He screamed in pain, and his mother came rushing in. He cried and said that his younger brother had pulled his hair. His mom said, "Well, he's only two years old, and he doesn't know what it's like to have his hair pulled."
The mom left the room, and seconds later, she heard another scream, but this time it was the two-year-old screaming in pain. She rushed in and asked what had happened, to which the five-year-old explained, "You said he didn't know what it felt like. Well, now he does."
