It's generally not appropriate behavior in most social and relationship contexts. Sitting on someone else's lap, especially when married, can send the wrong signals and may make one's partner uncomfortable or jealous.
One story could be when a couple was at a family gathering. The husband was feeling a bit tired and stressed from all the socializing. His wife noticed and sat on his lap, giving him a warm hug. She whispered kind words in his ear, reassuring him. It was a simple yet intimate moment that showed their strong bond.
You might also need to have a conversation with the friend. Politely express that such behavior is inappropriate given your wife's marital status. Maybe something like, 'I know you two are friends, but her sitting on your lap is not okay in our relationship.' And then, depending on their reactions, you can decide how to move forward. If they are apologetic and understanding, it's a good sign. But if they don't see the issue, you may need to re - evaluate the relationship with both of them.
In a 'wife sits on lap story', perhaps they are reminiscing about old times. They might be looking through an old photo album together, and as she sits on his lap, they laugh at the funny memories from the past. It's a sign of their comfortable relationship.
There was this couple. The husband was sitting on a bench in the park reading a book. His wife came running up and jumped onto his lap. But she misjudged the force and they both almost toppled over. They ended up in a heap on the grass, laughing uncontrollably.
Once at a family gathering, there were no more seats left. My little sister, being the cheeky one, just plopped right down on my lap. We then started sharing a plate of cookies, and I told her some funny jokes. She giggled so much that it made everyone around us smile too. It was a simple but very enjoyable time with her on my lap.
At Christmas time, the family was gathered around the tree opening presents. My little sister got so excited that she ran over and sat on my lap to show me the new doll she got. We then started making up stories about the doll, like it was a princess from a far - away land. It was a magical moment filled with the joy of the holiday and the closeness of siblings.
