“Strange how they leave me in here. Why pink? I don’t know. I understand the shells. There’s four inches of water in the tub. I swirl the shells around. Take the blue ones to make a geometric design. Then take the top jar; take out a colored paper; copy my design; drop it in the bottom jar; put the top jar back. Repeat, repeat, repeat…. I wonder why pink…. Swirling is soothing. I’ve always liked geometry. Back home I made figures on grids. Drew figures in the sand. I’ve always liked geometry. I’ll do it again…. Why pink? Don’t know.”

Thanks, Rochelle, for the 100 word prompt, and also thanks to Priva Bajpal for the picture. Rather baffling this week. Stretched my imagination. 😀

Oh dear… that person is totally stuck in a loop…
I have no special training in this kind of situation, but experience seems to show that when a person goes into mental illness he/she focus on something they really like. That was my reason for the “geometric design” issue, but other things are so strange. I had a friend who was a building contractor. When he entered a stage of dementia, his wife said he liked to make his bed. He would make it nicely, undo it, and remake it, seemingly enjoying it. I thought the “bed-making” might be a form of “construction” for him. A more knowledgeable person might laugh at my musings regarding the issue.
