So I have been using an artificial "fly" to catch fish lately. It is called fly fishing.
lol That sounds fun. How does it work?
Well in fly fishing we use a specialized weighted line to cast the fly.
Interesting!! tell me more 
Fly fishing requires a completely different technique because the fly or "lure" is weightless. It is much different from traditional fishing.
So I have heard. Is there something else I can learn about fly fishing?
You can fly fish in both salt or fresh water. It is a little harder to master than traditional fishing.
Wow this info is great! please do tell me more
The fly fishing lures are hand tied. They are made to resemble natural invertebrates to lure the fish into striking them. 
Thanks so much for the info!
