To b honest he has always been a bit frail in the brain department and has been getting worse since his mum died and since his cancer diagnosis. He has a tendency to fly off the handle or shout at the smallest things. The booze does not help

He called me on Wednesday ranting and shouting about some workmen in the house next door. I suggested he had a quiet word with the owners. This gentle suggestion appears to have tipped him over the edge

I have since had a string of abusive messages saying "Our friendship is over" and one this morning informing me that his "revenge" on me will be "ruthless and calculated"!

I checked in with a mutual friend who said that he had been round to see Nod and had been shouted at and threatened with a broom handle!!
What do we think: GP or Police?
