I’ve just completed one of those tasks which should be done from time to time, and that becomes much more so as one becomes older.
That has been going through my email address book and deleting those of old friends and comrades who are no longer with us.
I ‘ve also deleted the ones for people who are no longer working at various places for which I have their old email address.
Though just in case I did print out the list before undertaking the above task.
The sad thing is that it made me realise just how many of my friends have died over the last decade.
