Is never safe, regardless of ability. There are many variables that can occur while swimming anywhere. If swimming outside, a person has no control over environment shifts that could lead to hazardous occurrences in the water. There are also internal changes to the body that the person might not be able to control, such as sudden cramps or loss of hydration.

Ithink the answer is talking about their problems  

Afew buddies come over to your house to hang out. they notice you're struggling in school, perhaps you have to rely on to pass your class, but you can't absorb the knowledge. they could positively reinforce getting a tutor and working with you, dedicating more time to the areas of struggle and less on hanging out to better yourself.secondly, say you're the victim of bullying. you're afraid to tell an adult because of possible repercussions from the bully himself. your friends encouraging you and pushing you towards telling an adult for your safety is another example.
