That's a "suppose to" kind of grief.
I can list things I know about how grief feels. Lonely, isolating, sad, angry, depressed, hopeless, etc.
What I didn't know is how it can make your body feel. Lungs and heart seem to magically disappear making the chest cavity feel like it belongs to the Tinman. Swallow a marble and you'd most certainly have something resembling a maraca. The cavern ends in your stomach where it's been pierced through with a sword. Legs and arms have turned into wet concrete, heavy and slow to move while the head seems to not be attached, merely observing.
Loneliness rolls around inside the chest never allowing forgetting to quiet the echo. Sadness balls up tightly around the sword in the belly holding onto it tightly.
Laughter and fake smiles camouflage the tears and pain while a weak "I'm okay" escapes.
