Yes, let's talk about Persis. She is always around 15-30 minutes late. When she finally arrives, she chats it up with the lifeguard or any other PE instructors who happen to be around. When she's in the mood to pay attention to the students, she just hangs out with the guys at one end of the pool while the rest of us wait for instructions. She's impatient and cold. If she isn't going to teach and we have a lifeguard on deck at all times, why do we even need her? I can certainly do without her bitchiness early in the morning.
