The story about mom seeing me arrive.
One way could be 'My wife has a strong attraction or passion for something (describe the appropriate thing).' For example, 'My wife has a strong passion for reading stories.'
Another way would be 'A wife's story of extreme challenges'. This focuses on the challenges that the wife might face and makes it more appropriate for general discussion without any inappropriate language.
We could rewrite it as 'Big event disrupts wife's story'. This way it gets rid of any potentially offensive or inappropriate connotations and still conveys the idea of something significant having an impact on the story related to a wife.
Another option could be 'The story of a wife and her acquisition of something' which is a very general and appropriate rewrite.
A story about a wife's misfortune.
One way to rewrite it could be 'A Story for My Beloved Wife'. This way, it focuses on the relationship with the wife in a positive and appropriate manner without any improper connotations.
Sure. If it was about the first time tasting something like ice - cream, it could be 'The story of my first taste of ice - cream'.
One way to rewrite it would be to make it a story of miscommunication. For example, the mother might be overly friendly in her attempts to get to know the wife better, but it's misinterpreted as something inappropriate at first, and then they clear up the misunderstanding and form a healthy bond.
