Fishing

Sometimes I don't understand Jim and Jean.  At out house they have a little pond.  It has fish in it.  The gave the fish names and they take care of them.  They clean the water and feed them.  They really like their fish.  Then we go on vacation and the go fishing.  They try to catch fish with very sharp hooks.  Then they want eat them.  I just don't understand it.  I went with them and patiently watched while they went fishing.
