I decided to look at the questions once more and give my response.
Do you have a friend who you do not speak to anymore because of something that happened between the two of you?
Many years ago when I was a teenager I did that, the other person was (and probably still is) a compulsive liar and although I accept 'white lies' to protect a person's feelings, I hate deliberate lies. She told one lie too many and I went ballistic and told her never to speak to me again - and as she lived in the same road it was dificult. I finally spoke to her again about 10 yars later. These days life is too short.
You broke up with your boyfriend or girlfriend 2 months ago. You find out that your best friend hooked up with them at a party. Would you hold a grudge?
Nah, if I have finished with him she is welcome. I attempted to be friendly with my ex-husband's new partner/wife for the sake of the children.
The man who murdered your child is on death row. At the last minute, he asks you for forgiveness. Can you do it?
No, never.
You've contracted a treatable STD and you know from whom. Do you:
Never speak to them again
Tell them that you don't know if you can ever forgive them
Figure it's just as much your fault as theirs - Yes, I ought to have insisted on protection.
You go to your 20-year High School reunion and the person that teased you unmercifully all through high school is there. Do you:
Approach them and start up a friendly conversation? - Yes, that will make them feel guilty.

Avoid them like the plague?
Make polite conversation only if you have to
Would you be upset if someone at work took your lunch out of the refrigerator and ate it without asking even if they apologized?
Yes would forgive them, especially if they replaced it with some smoked salmon sarnies.
You lent a significant amount of money to someone a year ago. They still haven't paid you back. Are you mad at them?
No. Don't lend money unless you are prepared never to see it again. I would far rather give it. Mind you my ex-boss (of many years ago) borrowed ove Story from me and never returned it. When I visited her home is stared at me from the bookcase and I was too much of a coward to ask for it back!
Your friend comes to stay with you for 2 weeks. When they leave, the place is a total wreck. Six months later, they ask to stay with you again. Do you refuse?
No, just tell them that my health hasn't been too good so I will have to ask them to assist with shopping and cooking etc, and the washing up and hoovering...
You get food poisoning at a restaurant. Would you stop going there?
No, once they have been reported (by me) to public health they are going to be more particular in future so it would be a safe place to eat. I might well have told them that I got food poisoning from them and hope for a free meal.
Do you stick pins in voodoo dolls of any of your ex's?
No, I tend to remain on good terms, able to speak if I saw them.
