I ran into a doc and found out that a one-time sleep stroll is nothing to worry about. It happens when you're really tired or have a lot on your mind. Like a dissertation.
Speaking of... I wrote a long-overdue email today to my advisor.
Gained: Hopefully, the advice of someone whose opinion I really trust, and an ETA on my PhD.
Second, I went to Jack in the Box and asked for two free tacos. I didn't have the coupon printout for this national promotion, so I showed them the coupon on my my cell phone screen and the manager okayed it.
Gained: Free lunch!! (Value: $1.)
