A thought arrives and disappears.
A brilliant thought occurred to me in the shower in the morning, and I said to myself that I’ll keep repeating the thought in my head until I’m done with the shower and then write it down the moment I step out of the bathroom.
I remembered now, past midnight, that I was supposed to write down the thought I had in the shower, and I forgot it the moment I stepped out of the bathroom, and never remembered it again during the course of the day, I forgot to write it down, I forgot what it was.
Now it’s driving me crazy and I can’t sleep. I hope that the same thought occurs to me again, while taking another shower, maybe tomorrow, maybe 25 years later.
A thought arrives and disappears, perhaps to never arrive again.
