Here we go again!

Throughout my life, the one constant fly in the ointment has been Ireland.  And obviously this is a sequence not meant to be broken.  Here we are, on the cusp of an agreement with the EU which will enable the Brexit talks to progress and guess who's intent on throwing a spanner in the works?  Of course it's all our fault - we created the Ireland "problem" and it's only fair really that it keeps tripping us up.
