Pretty much just the title. Every Sunday we get together and play for 4 hours and honestly there are like 100 things I'd rather do. I love DnD shows and content (which I acknowledge aren't actually existing DnD) so I keep getting suckered into giving it a try.
I just hate to quit mid session because thats rude and is a pain to everyone else but also I don't want to spend 4 hours every Sunday on my day off doing something I'm not enjoying.
How do I end this lightly? Can I?
If you are willing to do one last round, I'd tell them ahead of time you plan to quit and see if you can get the DM to prepare some chain of events which allows your character to do some heroic self-sacrifice or embark on a voyage to a far-off land in your last session. Otherwise, people have real lives and they should understand if you are unable to keep going.
