There could be trouble ahead

Actually, there *will* be trouble ahead.

This is next doors magnolia bush. (yes, bush...tis a bit bigger than it should be)
She's a bit...how do I say this nicely....old and set in her ways? For example, when we moved in dad wanted to change the fence between us. It's on the side that she owns but dad offered to pay for half and put it up, it's falling to pieces. But she refused as 'it will damage her plants'.
It wouldn't in the slightest but there you go. So now we have a fence that is only just upright.
She also doesn't get anyone in to prune anything, hence the size of the 'magnolia bush'.
It all falls into our garden.
Hence the trouble.
Me and mum running around before dad gets back from work picking up all the petals and hoping there isn't a gust of wind - less chance of whinging this way!
