A woman suspects her neighbour of cheating on his wife and feels the need to let her know, after a similar situation happened to her, but others have told the woman to "mind her business" and to "keep out of it".
On a popular Mumsnet forum, she asked if she should write an anonymous letter to her neighbour, explaining her suspicions. She said: "I have found out that one of our neighbours appears to be having an affair. He is married with a child. We don't really know one another although I know his and his wife's names. I don't know the woman I saw him with. I don't know whether to post an anonymous note to his wife or not.
"I also don't know if my own experience is affecting my judgement. Years ago, one of my neighbours tried telling me my own husband was having an affair. She didn't do it directly and I didn't cotton on so it was only later when I found out about his affair that I realised what she had been trying to tell me. I felt grateful she had tried to intervene."
