I didn't sleep last night

These are a series of emails from my advisor. I put up a few just as examples. These are apart from the times when he didn't show up at all or called me on my cellphone. The number of meetings he missed speaks for itself. Apart from not having normal sleeping hours he would leave at 4 or 5pm to practice music with a friend, if , yes if he showed up. He was basically perpetually absent. 

The words in brackets are mine.

I did my best to stay awake for our 1pm meeting, got super strong coffees at the Pavilion, following my class [It was a 9:30 class], but just cannot manage anymore [then resign]; in fact I nearly got hit by a fast moving car on Sunset, which I did not even see. That really scared me. As I did not sleep at all last night, I will try close my eyes for a bit.

Sorry, but in need of some sleep, I propose to meet today at 2pm rather than 10am. Let me know if this does not work for you.

Sorry to bug you, but this is yet one more sleepness night, and I am concerned about possibly missing our meeting today at 10am.
Thus, if you do not see me in my office around 10am [So you mean I have to sit there and wait to see whether you manage to show up or not???], may I ask you to please give me a call, so that I do not miss our appointment [As if I am an alarm clock! ].

At 9 am the same day:

In fact, I am still awake after the night, so will make it, although perhaps mentally and physically on another planet [Not that other days are different] . At 12 noon I must return to the dentist, so should leave Rice around 11:15am.

My stupid advisor thought science happens by showing up occasionally while he is mentally on another planet! Good job!
