next door's hedge

I have just spent over an hour cutting down the side of my next door neighbour's hedge that flows over into my front garden. My neighbours are a young couple probably in their 20s. They cut the hedge at their side and half way along the top of the hedge.
I am incensed that their hedge costs me so much time, effort and money.
First I had to buy an electric hedge trimmer to cut the wretched thing. No matter what salesmen say about these things being light weight, when holding them above your head at arm's length they soon become very heavy. This one has 3 safety switches as a safety precaution, so a deal of dexterity is needed as well. I cannot reach the top of the middle of the hedge so it does not look too good. It is a bit hit and miss.
Then I raked up The cuttings and bagged them. Now I have to take them in my car to the tip.
The fun does not stop there. I have a 9 metre long back garden and I haven't started on the hedge that runs along the side of it, their hedge I must point out.
So am I being unreasonable or am I turning into a grumpy old woman.
I am exhausted now so I have lost my sense of humour.
