What anti drug lession might also be something a daddy fish would say to his son?

A daddy fish might tell his son to "stay away from the dangerous currents and dark waters," which serves as a metaphor for avoiding drugs and harmful influences. Just as certain waters can lead to peril, drugs can lead to harmful consequences. He might also emphasize the importance of choosing friends wisely, reminding his son that swimming with the right school can keep him safe and healthy.
