AITAH for 'humiliating' my neighbors kids by having them help me fix a window they broke?

Using a throwaway because I want to.

My girlfriend (25F) and I (25M) have been dating for about seven months. I moved into this house around six months ago because it was closer to my family and friends than my previous place. It’s a little farther from work, but I mostly work from home, so it wasn’t a big deal.

About a week ago, I was doing dishes in the kitchen when I suddenly heard glass shattering from the garage. When I went to check, I found broken glass all over the floor—one of the windows (not the door) had been broken from the outside. I didn’t see anyone, but while cleaning up, I found a football that wasn’t mine. I recognized it as one of my neighbor’s; I had seen their kids playing with it in the front yard before.

Later that night, my girlfriend noticed the broken window when she came over for dinner. She doesn’t live with me, though I have asked her a few times. I mentioned that one of the neighbor kids must have accidentally broken it while playing football and that I’d return the ball to them the next day. I wasn’t angry about it—it was just a window. But my girlfriend seemed annoyed and called the kids “rude” and “disrespectful” for not apologizing.

The next day, I went out to get supplies since it gets cold where I live, and I wanted the window fixed sooner rather than later. When I got back, I grabbed the ball and knocked on my neighbor’s door. The mom answered, and after I explained what happened, she had her three boys come and apologize. She also offered to pay for the damage, but I declined. Instead, I asked for one thing: that the boys help me fix the window.

I thought it was a good lesson. When I was a kid, I used to ride my bike through an elderly lady’s flower garden as a shortcut. One day, she caught me. Instead of punishing me, she asked me to help her replant it. So, I spent a few afternoons after school helping her, and that experience really stuck with me. I figured this was a similar opportunity for these kids.

My neighbor agreed, so I showed the boys how to fix the window. At first, it was a little awkward, but they warmed up to it and actually did a great job. About 30 minutes in, my girlfriend pulled into the driveway. She gave me and the boys a weird look but went inside without saying anything.

After we finished, I thanked the kids, sent them home, and went inside. My girlfriend immediately asked why I had them help. I told her I thought it was a good way for them to learn from their mistake, just like I had when I was younger. But she said I had humiliated them. I explained that I wasn’t trying to shame them—I wasn’t angry, didn’t make a scene, and even turned down their mom’s offer to pay. I just thought it was a good way to teach them responsibility.

She still thinks I was in the wrong. I don’t think I am, but I also don’t want to go around awkwardly asking my neighbor’s kids if they felt humiliated.

So, AITAH?
