Hello fellow writer. Happy Account Anniversary. You have taken the concept of somebody being a strong, solid rock and revealed the flip side. You raise the question and very real possibility that that same person could collapse under the weight of all they have carried for others. Even an actual rock is not indestructible, so why do we expect a person to be? Everything and everybody has their stress load limit. Rocks develop fissures. Like a rock a person can only weather so much. The first three stanzas describe the reliable, steady practical and kind figure selflessly helping others. We all know people like this and sometimes, we lean on them because we wish for that strength. The following question is something many never consider. "But what happens when this rock starts to crack?" "But what happens when the foundation grows soft?" I like this imagery of a building collapsing. Once it does there's no longer any structural support. Who becomes the new rock for the selfless, giving, sacrificing one? I cannot fathom carrying the weight you mention here and then crumbling with it. The rhyme of this poem feels natural and unforced. Thanks for sharing this.
