Note to self:

This was a fantastic night/morning (it is 3:06 am).

When you volunteer to spend all day at a workshop on diversity and multiculturalism on a Saturday again, make sure you once again make up for the lost you-time by having a tiny wine-and-cheese-and-Nintendo gathering (I guess it won't be spontaneous as it was tonight if I am planning it now), and stay up until the weeeee hours -- as long as it takes until you have done not-work longer than you have done work.
(It did say "note to self" above; what did you expect?)
