It could be that the son's friends took advantage of the mom in terms of money. For example, they might have borrowed money from her and never paid it back. Or they took advantage of her hospitality. They visited often and ate her food but never showed any gratitude or respect. They might also have made the mom do a lot of work for them, like cleaning up after them when they made a mess at her place, thinking that she was just there to serve them because she was the mother of their friend.
Perhaps the son's friends exploited the mom's kindness, like asking for too many favors or using her resources without permission.
The son can directly confront his friends and tell them to stop taking advantage of his mom.
One 'took advantage of mom story' could be about a kid who took advantage of mom's kindness. For example, the kid knew mom would always make his favorite meal when he pretended to be sick. So one day, just to have that meal, he faked being ill. Mom, being the caring person she is, made the meal, and later found out the truth.
There could be several reasons. One possibility is that they are in some kind of trouble themselves and think blackmailing the mom can solve their problems. For example, they might have debts they need to pay off. Another reason could be that they are just bad - natured kids. They might enjoy having power over someone and see blackmail as a way to get that power. Or perhaps they have some secrets that they don't want the son to know and they are using blackmail to keep the mom quiet about those secrets.
One lesson is about honesty. In a 'took advantage of mom story', often the person taking advantage is being dishonest. We should always be honest with our moms. For example, if we pretend to be sick just for perks, it's wrong.
Maybe they went to a quiet place to have a private chat. It could be that the friend wanted to share some important news or just catch up away from the noise of the party.
This is an inappropriate and uncomfortable topic. We should focus on more positive and appropriate subjects.
First, you should distance yourself from your son's friend immediately. Then, you need to talk to your son about what has happened, but be careful not to put too much blame on him. You may also consider reporting the situation to the appropriate authorities or seeking help from a counselor. It's important to protect yourself and make sure this doesn't happen again.
First, you should firmly tell your son about what his friend has done. Then, depending on the nature of being 'taken advantage of', if it's a financial matter, you may consider asking for compensation or taking legal action. If it's an emotional or personal matter, make sure to set clear boundaries and keep your distance from his friend.
It's possible that the son was influenced in some way. He might have seen different values or lifestyles among his friends. If his friends were very studious, he could be inspired to study harder. After visiting, he might start to change his daily routine or hobbies based on what he experienced there.
I'm not sure specifically what this 'mom taken at son's party' story is about without more details. It could be that the mom was suddenly called away during the party, or perhaps she got involved in an unexpected situation at the party.
