Sharing such stories involves private and inappropriate content, so I can't provide relevant stories. We should respect privacy and propriety in communication.
Maybe the stories are about a big rooster that has some extraordinary behaviors. For example, it might be very friendly towards the wife and follows her around the yard all day, which surprises her.
I know a story where a friend of mine received a letter from an old schoolmate she hadn't heard from in years. The letter was full of memories and how much that person missed their friendship. It was a total surprise and it led to them reconnecting and now they are great friends again.
There was a couple who went on a beach vacation. The wife was wearing a new bikini top. One day, as they were walking along the beach, a strong gust of wind blew. The wife's bikini top got loose and was about to come off. She quickly grabbed it but was still in a rather topless - like state for a brief moment. Her husband was very surprised, and they both had a good laugh about it later. They even took it as a funny memory of their trip.
In a story, the big rooster might have chased away a potential predator from the yard. When the wife sees this brave act, she is very surprised. The rooster, which she thought was just for eggs and decoration, turns out to be a great protector.
There was a time when the wife always talked about how she missed her hometown. So, the husband made a surprise trip for her. He booked the tickets, packed their bags, and on a normal weekend, he told her they were going on a short drive. But instead, he drove her to the airport. When she realized they were flying to her hometown, she was extremely surprised and overjoyed. It was a great adventure that made their bond stronger.
Yes, it can be normal. In a healthy relationship, sharing such stories might be a form of sexual communication and intimacy. It shows that she trusts you and feels comfortable enough to share this aspect of her thoughts or experiences with you.
Buy her something she has been eyeing for a long time. It could be a piece of jewelry, a new book by her favorite author, or a gadget she would find useful. And don't forget to write a heartfelt note to go along with it.
It's not a common trope in literature overall. But in some works that explore the darker side of human relationships, it can be found. In these stories, the hubby's surprise can be a catalyst for various things. It might lead to him seeking revenge, or it could cause him to question his own worth and what he did wrong in the relationship. It also often delves into the wife's motives for having a lover, which can be due to dissatisfaction in the marriage, a search for excitement, or other complex reasons.
Well, it depends on the nature of the'surprise'. If it's something positive like her best friend did an unexpected kind gesture, then you can show your appreciation. However, if it's something a bit off - like her best friend overstepped some boundaries - you need to discuss with your wife how to handle it without ruining their friendship.
