Let's go fishing

I like to go fishing. My dad and i always go fishing at the weekend. Actually i do not know how to swim.
I have been taught how to swim many times. But in the end i still cannot swim. I respect those who know how to swim.
After we fish, we like to cook fish and chips. It is delicious and easy to make.
To cook the fish you have to clean it first then cut it into slices. Then add one cup of flour and a little bit of water into the bowl. Stir it. After that put the fish into the bowl.
Put some oil into a pan. Then cook your fish until it starts to turn a bit brown. It's easy like abc. Everyone should try to make by themselves.
In addition you can save money rather than you buying it. You can also save money by fishing instead of buying fish.
