If you could fly.

How would you convince someone you could fly without showing them? What would your reaction be if your friend told you he could fly?

How would you convince someone you could fly without showing them?

I wouldn't be able to convince anyone unless the person I was trying to convince was extremely gullible or an idiot.

What would your reaction be if your friend told you he could fly?

I wouldn't believe them.

Get someone who has seen u fly and have that person show a video of u flying.

That way u didn't show them your friend did. Loop hole.

The only answers that make any sense, really.
