After doing your best to hold a grudge: something you've never been any good at: a peaceful wave washes you away from it, even if a friend did something that feels like absolute treason to you. You'll wake up feeling compassionate, and ready, finally, perhaps, to accept the apology. Still, while forgiving is a good idea, don't feel bad if you're not quite able to forget. It's called wisdom, and it comes with experience.
