Because I was groggy, I left my laptop at home.
Because I left my laptop at home because I was groggy, I missed a deadline to retrieve it.
Then I was late for a meeting because I was late with the deadline because of the laptop being left because of the grogginess.
I lost the following meeting because I didn’t read my email because I was late for the first meeting because I missed the deadline because I left my laptop.
Then it started to rain.
