I would like to try fly fishing 
Fishing? What is that?
fly fishing is an angling method in which an artificial fly is used to catch fish I have never been but would like to 
I have never done that either. Can you tell me more about it? It sounds fun
you cast a nearly weightless fly it requires casting techniques significantly different from other forms of casting
I see, it must require a lot of precision right? I am not very good at fishing.
yes it requires precision but you can do it fresh water or salt water so there are place around where I can go practice
I might go practice today since I have time. Do you like fishing in fresh water? 
yes I like fishing in fresh water and the fly line they are today almost always coated with with plastic is heavy enough to send the fly to the target.
I dont think plastic should be used, since its not environmentally friendly!
