1) Yes definitely. I would never wish tor hurt anyone especially their feelings.
2) If they mean it then I would feel much better. That means they genuinely feel bad for what they did and wish forgiveness. Then we can get back to being happy and not all sad.
3) Yes I do. I do not like grudges, for grudges just brew hatred, and hatred is something this world needs less of. Forgiveness is an attribute of the strong. It would also be very easy for me to forgive if the person genuinely wishes forgiveness.
4) I usually do though depending on the amount of praise I may fee a bit embarrassed.
5) Yes it does. Makes me feel like I did a good thing.
