Grandparents are important because they tell you what happened in the past, which is always interesting to hear. What they say, might be important for your class topic. You can tell your teacher what they said then maybe something good might happen or you can write what they said in your book.

Or if it's something bad that had happened, maybe they're trying to warn you that it might happen again, so listen to them if they are giving you advice. The great thing about Grandparents is that they might give sweets or toy or other nice stuff like that!
