Erin realized tonight that Sean had one of her pens, and she immediately took it. Sean asked if he could have it back since he had been using it for his homework over the past few days, but she wouldn't budge. It was hers, and that was that.
A few minutes later Erin walked over to the table where Sean was doing his homework, set this down next to him and walked away.
In situations like this she almost always starts to feel bad and ends up trying to do the right thing. I told her how proud I am of her, and that is made me and Sean happy that she was willing to give him back something that he used and she didn't, regardless of whether it belonged to her or not.
