Shape. Whatever that means. Forms. You can study the symmetry of symbols we use in written language, words. Formless, shadows, we count them, bend our fingers around, call them dragons, call them dreams. Non-euclidean. Shapes that can't exist. Memories, shapes our minds have been forced to hold. Thoughts, shapes our minds create to deal with hope and fear, which... which perhaps I have a difficult time distinguishing between. Angular, curvature, some caricature of what I thought I'd be at 24. 24. Two shapes, angular and curvaceous.
I think it would be interesting to explore how time shapes memories, and how memories shape our time, or, what we perceive to be time and memories. Overall, though, I really enjoyed your story.
