In To Kill a Mockingbird what doesTom say Mayella did to him while he was standing on the chair, after he got down, and afterward.

The answers to these questions can be found through a
close reading of chapter 19.  In this chapter, Atticus questions Tom Robinson on the
stand, and he gets a chance to tell his side of the story.  Mayella asked him to get
something off of the dresser, and so he gets up on the chair.  While he is on the chair,
she grabs him around the legs; this throws him off balance, and he hops down, knocking
the chair over.  Then, Tom states, "she sorta jumped on me."  So, she jumped on him, and
hugged him around the waist, then kissed him on the side of the face.  He tried to run
out, but she grabbed him, so he had to push her away.  At that point, Mayella's dad came
in, and Tom ran away.

That is not the story that Mayella
and her father tell, however.  Atticus, through his questioning, makes it pretty clear
that they are lying and that Tom is telling the truth. I hope that helped; good
luck!
