Awkward moment

Yesterday my co workers and I went to a mandatory training.  I will grant that if you have been in our particular industry for more than a year, none of what was presented was new.  However it is also mandated that one attend annually.  Unfortunately my boss fell asleep.  And the newest person who was hired at our site noticed and asked me afterwards if he would have to attend another training because he slept through this one.  Sigh.  Truly an awkward moment. I don't know how many other people noticed--I didn't actually because I was not sitting near him--but this does not bode well.
