Carol says, "pam, you're my oldest friend in the world. i just inherited a million dollars, and i want you to have some of it. come with me to the bank tomorrow, and i'll give you $10,000." "awesome," pam replies. later that day, carol changes her mind. can pam force carol to pay her the $10,000?
No, she can't.
Pam cannot force Carol to pay her the $10,000 because it was just a promise by word of mouth and she did not sign any paper in order to give her the money. And also Carol can change her mind because although Pam is her friend, maybe she has more important people to help in her family.
