How do you get your big sister to play Littlest Pet Shop with you?

Answer 1

Realistically, there are two possibilities. Possibly there is something that you can do for her, in exchange. Friendship is a process of mutual benefit. She does something for you, and you do something for her. But possibly there is nothing you can do for her. In that case I would just have to advise you to find someone else, who would enjoy playing Littlest Pet Shop with you.
