I am really sorry for this. Thursday was last working day last week (as Friday
was holiday in India), so I thought I should ping you so that this series would
be reviewed by Monday. From now on I would try to keep a gap a week (or
whatever is appropriate) before pinging you for review.

I am really sorry for this again.
