No, such stories are not very common. Hospitals are generally places where people are focused on their own health issues or the health of their loved ones. Most people try to be polite and understanding in a hospital environment.
Perhaps in a hospital setting, a wife mistakes a stranger for a staff member who she thinks has made a mistake. Say, she's been waiting for a long time for her husband's test results which were misdirected. She sees a person who looks like a hospital employee (but is actually a stranger) and blows up at them, thinking they are responsible for the error.
It could also mean that the wife has an impact on a stranger's opinion or view. Maybe the wife is an environmentalist and she gives a passionate speech about protecting the environment. A stranger who overhears her is so influenced that it's like she 'blows' his previous unconcerned attitude away.
Ethically, it is wrong. A wife has no legitimate reason to spy on a stranger. This act violates the fundamental principle of privacy. It can create an uncomfortable situation not only for the stranger but also for those around her if they find out. If there are concerns or issues, they should be addressed through proper channels rather than spying.
One possible story could be that during a vacation, a wife met a stranger who was an artist. The stranger was painting a beautiful landscape near the beach where they were staying. The wife, being interested in art, started a conversation with him. They talked about different painting techniques and the beauty of the place. Eventually, they became friends and the stranger even gave the wife a small painting as a souvenir of their encounter.
One famous story could be that of Abigail Adams. She was a remarkable wife. Her letters to her husband John Adams were full of wisdom and advice. She 'blew' him away with her intelligence and political acumen, which was quite extraordinary for a woman in that era.
No, it is completely unethical. In a committed relationship, such behavior violates the trust, respect, and boundaries that should exist between partners. A marriage or relationship is based on mutual fidelity and loyalty, and any form of inappropriate behavior towards strangers goes against these fundamental values.
There could be a fictional story where 'wife blows stranger' in a positive way. Suppose a wife is a magician. She meets a stranger who is feeling down. She then 'blows' (figuratively) the stranger's mind by performing a magic trick that completely changes the stranger's mood and gives him hope and joy again.
A wife once had a flat tire on a lonely road. A stranger stopped to help her. He was very polite and quickly changed the tire for her. She was initially a bit wary but soon realized he was just a kind person. After that, she always remembered this act of kindness from the stranger and it made her more open to helping others in need as well.
In most cases, it can be considered indecent exposure which is illegal. However, the specific legal implications can vary depending on the jurisdiction. There are laws in place to maintain public decency, and such behavior may violate those laws. But it's also important to consider if there are any extenuating circumstances, like a mental health issue.
