Sometimes too big of heart. I try to help many people in form or other

It's a mushy heart but it's guarded well.

I used to have a heart of glass that turned to clay; now it is a bit harder.

I don’t know. It doesn’t appear to break. It seems to grow with age. It’s strong but not a rock, as it’s penetrable by love.

Stone 🪨

Depending on the person and situation my heart is as hard as stone or as open as a house with no doors.

It was of glass. I heard/felt it break.

Actually, it's glass melted into a porous stone and there are some air bubbles here and there.

I have a marshmallow heart. People eat it, but it grows again...:))

No heart here

Let me go look for it and then ill let you know

Fibreglass

I have one, but what it is made of is open for debate. It very much depends on who you ask. Me, i really don't know. It's an unpredictable darn thing.

I have a heart of gold — hard, cold and yellow.

A heart of plaques, most likely.

Heart? Whats that?

I have a heart of glone.

It is made of potpourri and dandelion fluff.

A heart of glass guarded by a fortress of stone.

Heart of jello
