I have positive feelings toward my sister who was mean to me. Does this wrap up forgiveness for me then? In other words, are positive feelings the gist of forgiving or is there more to it?
Positive feelings by themselves are not the end of the forgiveness process. If you think about it, positive feelings by themselves can be passive. For example, you feel positively toward your sister as you sit on the couch and never make a positive move toward your sister. As a moral virtue, forgiveness includes thinking, feeling, and behaving (within reason) toward the one who hurt you. When you forgive, you are open to the possibility of reconciliation with the other. This openness toward reconciliation is not an automatic coming together again. The other has to be trustworthy for the reconciliation actually to occur.
