Apology

Due to an impending course that's going to have me away from
my desk for two weeks, my arrival at the next checkpoint
will be somewhat delayed...

Auntie Anna

The tall blonde chick, jumping around with a guitar, is my
uni colleague, Anna. The guy who gets his head shaved is her
partner Mark. The little kid is Anna's nephew Michael, and
Michael's assistants are his parents Louise and Alistair.

Mark's nephew, Joe, is being treated for leukaemia (I think)
and has lost all his hair, so ALL the men in their family
are shaving their heads. But only Mark has put it on youtube
and sent it around the uni.
