What is the meaning of "wait" in the following context:
The Mom want to move to another place. One of her daughter has got so mad at her because the daughter didnt want to leave. The daughter yelled at her mom saying:
"I can't believe you waited to do this"
1st sister: She didn't wait.
the daughter: yes, she did.
2nd sister: She doesn't know.
The daughter to her mom: Yes, you did wait!
So now can I know the meaninf of all of these "wait"s?
Thanks a lot.
