Moved into my co-op building here in Westchester-County NY almost 4 years ago. My first son was just born. There was a girl, Sarah, one floor up and one apartment over who's a little older than my kid, but they get along fabulously. He talks about her more than he talks about his cousins. About two years ago, Sarah's mom leaves a note with my mother-in-law (my MIL watches my kids during the day while the wife and I are at work) asking if Tyler (my son) and my MIL want to go to the park tomorrow with Sarah and her mom. My MIL is 72 years old, obese, severely diabetic, and is afraid to take my son to the park because she can't keep up with him. Knowing how much this would mean to my son, I take off of work and take him to the park - he and Sarah had a blast. I have a side-business as a photographer and brought my camera with me - took some photos of the kids and a few of Sarah and her mom. The next day, I see the mom in the hallways of our apartment building, she sees me, lowers her head, and doesn't even say "Hi". Weird. A few days later I've processed and printed out some of those photos in 5x7s and Tyler and I go up to their apartment and deliver them. The mom opens the door and instantly this weird look comes over her face - I hand her the pictures, she doesn't say a word - nothing, doesn't even acknowledge my son who's standing next to me. I went back downstairs and told my wife how weird that was and that I think Sarah's mom had a black-eye when she came to the door but it might have just been a shadow. Again, that was two years ago. The mom has barely spoken 4 words to me in total since then. She'll occasionally speak to my wife in extremely shorts bursts, but never me and won't speak to either of us if I'm around. Her husband is really nice to us, always quite talkative, works a lot so we don't see him often, but generally speaking he appears to be an okay guy. Fast forward ... This weekend our power was out. Put my kids to bed Friday night, and the wife and I knocked on our neighbor's door (the ones directly below Sarah) to check on their kids for them (the kids are teenagers and were home alone). We get to talking because there's nothing else to do and they fill us in on all the times they've had to call the cops for the guy upstairs beating the **** out of his wife. Now everything makes sense and my wife and I feel like utter crap. We've been pissed at her because we think she's being snooty or something, not letting her daughter play with my son, but the reality is that she got a beat-down because she went to the park for 3 hours with another guy who's younger and in much better shape than her husband. I know, I know, if she doesn't press charges (which we all know she'll never do) - there's nothing anyone can do. But is that really true, is there nothing we can do? I've never seen Sarah with a bruise, but if I do can I press charges or does it have to be a parent/guardian? Short of putting both mother and daughter up in a home and financing them ourselves (which if we had the cash we'd do in a heartbeat) ... is there anything we can do to help? I actually asked a friend this weekend who's an NYPD sergeant and his advice was to put on a ski mask and issue the guy a solid beating in the hallways - not exactly very "useful" advice.
