It might be this: You can show leadership in many ways in PE. One way is to ALWAYS play fairly, never play unfairly. Another way is to never brag. It's mean to, don't say haha I WON y'all lost!! It is very rude.Instead say Good game or you did great. Also don't show off, it is also very rude. Never lie about you winning even if you didn't win, that is just not being honest.
Hoped this helped!!
