How do you get by the old man on Pokemon FireRed?

You're likely referring to the old man blocking the way to the Viridian Forest in Pokemon FireRed. To get past him, you need to answer his trivia question correctly.

Here's how it works:

1. Talk to the old man. He'll ask you a question about Pokemon.

2. Choose the correct answer. The answer is always related to the type of Pokemon he's talking about.

3. If you answer correctly, he'll move out of the way, allowing you to enter the Viridian Forest.

4. If you answer incorrectly, he'll tell you the correct answer and ask the question again.

Note: The question and answers may vary, but the principle remains the same.

Tip: If you are unsure of the answer, you can always try to guess. You have unlimited tries, so don't be afraid to take a chance!

Good luck getting past the old man and into the Viridian Forest!
