You don’t owe anyone an explanation. You don’t owe anyone anything, just as you aren’t owed anything in return.
You don’t have to spend the time convincing other people to agree with you. You don’t have to spend the time explaining and hoping that you can make them agree.
Sometimes it can be useful.
But a lot of the time you can just get on with doing what’s best for you.
Don’t worry what other people think.
Instead, focus on living life your way.
