One common story could be about a mom teasing her son for being clumsy. For example, when the son accidentally drops his books, the mom might say, 'Oh, look at you, Mr. Butterfingers!'. Another could be teasing about his first crush. If the son has a little crush on a girl at school, the mom may tease him gently like 'I saw you blushing when she walked by!'.
Create your own private space where you can go when she does this. For example, you can have a room where you can close the door and be away from her when she's acting this way.
No. Sharing such personal and private stories, especially ones that are inappropriate in nature, is not acceptable. It violates privacy and is disrespectful to your wife.
A mom might tease her son when he's trying to grow a beard. She could say, 'That's not a beard, it's more like a few lost hairs trying to find their way home.'
Sure. Once, a mom teased her son by saying he walked like a penguin when he was learning to skate. He got a bit embarrassed but then started laughing at himself too.
Sure. There was a mom whose son was always into building things. One day, he built a little wooden box that was a bit wobbly. The mom teased him, 'Well, this box looks like it's had a few too many shakes! But I'm so proud of you for trying.' The son laughed and then they worked together to make it sturdier. It was a simple moment of teasing that was also full of love and support.
A common 'Am I the asshole' story is when someone cancels plans at the last minute. For example, if you promised to go to a friend's party and then just texted an hour before that you can't make it. It's a bit asshole - ish. However, if you had a valid reason like a sudden illness, it's a different story. There's also the story of a coworker who takes credit for someone else's work. That coworker is most likely the asshole in that situation.
