ok, this goes too far

I just went to see my microbiology-professor to hand in my protocol.
Walking there, I spot him with 2 students, explaining an ultracentrifuge to them.
The following conversation took place:

Me: “Hello! Can I give you my protocol right away? I was in the building and before I forget to bring it tomorrow for the exam I thought, I better leave it here where it belongs”
Him: “You know the exam takes place today”
Students: *snicker*
Me: *makes big eyes*
Him: “It was you suggesting this date if I remember you right.”
Students: *laugh*
Me: “Yes, of course, I just confused myself… err.. thanks and till later”

I walked away with a most unpleasant feeling. How can one be so confused???

Even worse: What, if I had not decided to pass by and hand in my protocol?
What if I had not confused my workshifts at the helpdesk? initially I planned to work from 10 o’clock till 1900..
Someone out there really loves me and takes care of me! I love this life :D

On the other hand, that’s probably just the usual chaos that I tend to accumulate around me ;)
