conversations.value: I need help with this problem:
  Bush and Matt are brothers. Bush is younger than Matt by 3 years. This year Bush will be 12 years old. What will be Matt's age 10 years from now?
conversations.from: assistant
conversations.value: Bush is younger than Matt by 3 years, so if Bush is 12 years old then Matt is 12+3 = 15 years old
  In 10 years' time, Matt will be 10+15 = 25 years old
