My neighbour, whose back garden is adjacent to my back garden, has been exposing himself to me for about 18 months. At first I saw him watching porn in the spare bedroom. Thought nothing more of it. I'm not a prude. But the TV was a large TV and it was right up against the window, with the screen facing outwards so I could see everything. I used to sleep in the big, front bedroom, but my teenage son nagged me to have the large room for his TV, X BOX and all his gadgets, so I agreed. Moved my things in to the small room at the back and a few days later was when I noticed the porn. Then I started waking up to different porn magazines on my back door, open at specific pages. Usually of a woman giving a man a blow job. As if whoever was leaving the magazines was sending me a message. Then early one morning he was sitting in his back garden in nothing but his dressing gown. His dressing gown was fully open and he was completely naked underneath. More porn on the TV. Always Friday, Saturday and Sunday evenings when his wife was out working at the local Chinese takeaway. Then things escalated. He started coming in to his back garden whenever I went out to put clothes out on the line. Then one day he was sitting in the chair in his back garden, with his dressing gown on and was naked underneath, but he was masturbating. I told a friend of mine, who is a local Councillor. Not that I wanted him to do anything, but just so I had it written down as evidence that I had told someone. Another time in the back garden. I had just gone out to either put some clothes out or to bring them in, and suddenly he emerged from his house, dressing gown on which was undone. He was completely naked underneath. He started walking towards the fence, with his dick in his hand. I just turned on my heels to go in. But before I did I shouted, "I WILL report you to the police if you carry on you know". He practically ran inside his house shouting, "I'm sorry, I'm sorry". Nothing for months, but recently I have been able to see right inside his house and he is walking around near the window completely naked. Always while his wife is at work. I'm telling you all this, because I was going to tell his wife exactly what kind of a man she is married to, and exactly what he gets up to in the evenings when she is at work. But she is such a nice lady. In the end I didn't have the heart to. But if it ever starts up again I WILL go to the police and press charges. But I said nothing not for his sake, but for his wife's. But OP, if that was my dad who was carrying on [or potentially thinking about it] I wouldn't protect him.
