Yes Alex - my trying to "understand what you said" is a matter of my following your thought processes, so yes the problem is at my end of the phone line if you like!
I thought you may enjoy my input - my having 2 bob each way as it were - and adding a little fuel to the fire of debate.
May there be many more such thought provoking chats - in fact I have a topic in mind, I've been keeping it "on hold" for a couple of days for when we need something new.
