What is an example of a withdrawal from someone's emotional bank account?

a)Each person in a group project is responsible for completing certain work, and you get yours done early to see if anyone else needs help.
b)The newest pattern is at your favorite craft store so you trade an evening of babysitting the owner's son in exchange for the pattern.
c)You get to class only to realize you do not have your homework, so you copy your neighbor's answers when he is not looking.
d)Your elderly uncle wants to learn to use the computer so he can communicate online with family, so you help him learn the basics.
