This is a real one, gulp, if IABU be diplomatic please 
Our neighbour is a bit of a laid back chap lazy and not really a practical sort and in his garden a tree has fallen down.
We don't really speak or neighbour with them but my DP asked if neighbour wanted him to move the tree. We have a real fire and DP was convinced the tree wouldn't be moved otherwise.
Today he borrowed a chainsaw from his work and we went into next doors garden to chop up the tree.
After 5 minutes next door but one (our neighbours neighbour) came to the fence and demanded to know how long we would be.
Not in a conversational way I mean REALLY making a point of yelling 'Excuse me' at us.
She said she wanted to know because the chainsaw noise was scaring her ds, I said as soon as possible and my DP said 10 minutes.
She took her ds in and we hurried up.
Because she had said it was upsetting her ds we actually cut the tree into pieces so big they took 3 people to move, to saw later with reciprocating saw.
As we struggled to lift a massive bit of tree over the gravel board into our garden she bobbed back up at the fence and angrily wanted to know if we had finished.
DP told her yes, so she informed us 'fine I will fetch my ds out again to enjoy the garden'
I got the rage a bit hot, sweaty and carrying a ducking tree wasn't making me super patient as she stormed off to fetch her ds I asked 'why is she angry?'
She didn't hear/answer so we carried on shifting the tree.
Then she came to the fence with her ds and her two visitors to supervise us tidying up 
Now I know the chainsaw was noisy but here is my reckoning,
We weren't dicking about making ice sculpture we were very obviously doing a job that needed doing.
My DP was still in his uniform (army) so it clearly wasn't going to be an all night thing.
It was 14.00 on a Tuesday afternoon so not an unsuitable time.
Whilst I would do my best to avoid upsetting her ds this was one of those things she should have comforted him, not expected life to stop.
Or am I being an U twat?
