When somebody dies, we rearrange ourselves around the ones left.
Ain't that the truth. And for the first months, we do it very, very tightly, as if afraid to let them out of our sight.
life starts rearranging itself almost immediately. The inner geographies of your life start bridging over the sudden gap. Tears come through long spells of normal. Lust for life rushes over you. Primal.
Of course, it depends who it is, and your relationship.
Of course it's okay to not mourn your 'bad' Aunt - we are remembered by the relationships we had with people, and she sounded like a right terror. Compassion is one thing, forced grief is quite another.
