"I'm not going to," Peter says, attempting to pull himself off the ground. But as he gets himself up on his own two feet, he finds his legs aren't able to support his weight and he falls back to the ground.

Embarrassed, he attempts it again before he finds himself back in the same place.

Peter could attempt a third time, but he knows what's going to happen and trying it again is going to be more embarrassing than the first two attempts.He really shouldn't have pushed himself.
