Stiff,
At least you knwo to call concrete concreter. You'll be surprised how many people call it cement (Zedn - no you don't need to step in here mate - I know you want to, but you don't need to
).
You must feel for your neighbours especially with the fruit trees - you get used to your surroundings especially after 25 years!
Then who comes along - a Cobrafelilite banging and carrying on who needs a Grand Auditorium to place his toy
You'll need to hand out your olive branch Stiff as Neighbours can play hell with your head if it gets out of hand - Good luck!
