Some of you might have seen me post about this before my name change.
I have a severely autistic little boy who also has an array of health problems and other disabilities.
Anyway the man who lives next door, he's 93, this is relevant to the post as he hasn't always been this horrible so I'm thinking it may be related to a condition, which makes me feel worse.
Anyway he is really horrible, he bangs on the wall if I hang a photo up at 12 in the afternoon (so the hammering may have been 30 seconds on my part, lasted 30 minutes on his) he leans over the fence threatening to hit my little boy and any of his friends that I look after if any of them is having a crises. My child and his friends are by far the quietest on my street, I think he does this because he thinks he can smack the disability out of them 
Had him intercepting me when I was trying to leave my house every day for a year over the fence, a panel blew down, I wanted to replace the panel, he wanted the entire fence replacing so I bought the panel, he wouldn't let me put it in, eventually his son came round and put it in and all that stopped.
He has threatened to take me to court because he found a spoon in his garden and thought my son had put it there (it wasn't my spoon)
He leans over the fence and shouts at me for pulling my weeds out the wrong way and says that it'll affect his garden. (I'm not sure the right way of pulling weeds but never mind)
He has leant over the fence and shouted at and tried to hit my son when he was playing on his swing, scaring him to death and causing a seizure.
This is to name a few things.
Anyway I spoke to a friend about it who said to write down all the things he does from now on, with dates, and if he starts harassing me again to just tell him I've taken legal advice and to put anything he wants to say in writing.
Anyway, all was quiet for a time (I have been avoiding the garden though and running to my car) until today when I had to go out to mow the lawn and do some weeding.
He leant over the fence and said "hurricane, a minute" I hate confrontation and just said "I can't" he then said "just a minute" I said "I can't Sam I'm not allowed, just put it in writing" (not at all what I was told to say really but u felt really sorry for him and just wanted him to stop without confrontation)
He then said "two panels need replacing" (I've had a look and they're all fine) so I just said "look I can't talk to you, I'm not allowed, please just put it in writing if it's urgent"
He then laughed and started muttering to himself but walked inside.
It's going to start all over again isn't it? He doesn't take me seriously because I'm a young girl on my own. He's said as much in the past. But I feel really nasty ignoring him like that.
But on the other hand I know I have a duty of care to my little boy and I need to keep him safe.
Please tell me I'm haven't just been a massive bitch to someone with problems of his own
