1. Usually, but there’s always exceptions. I’m not going to apologize to someone I don’t think deserves it.
2. Again, usually. If someone is repeatedly doing something that warrants them apologizing over and over again, then it starts to lose meaning. And somethings go beyond just saying sorry.
3. I forgive pretty easily, but I really don’t think that’s to my detriment. Forgiving someone doesn’t mean you have to interact with them or let back into your life. You can forgive someone while wanting nothing to do with them.
4. Yes, unless I forget.
5. Honestly, no real preference. If someone says thank you, cool. If not, that’s cool too.
