All of that can make for a thorough, though unintended, education in the importance of managing one's Life Finances. Knowing about the "tough times" is part of sharing membership in a Family.
These days, many Families feel compelled to shelter their Children from all of the details which are causing such torment in the Lives of the Adults . . . . and may be denying them an important education. To avoid embarrassment and keep the neighbors from knowing, they do everything they can to also prevent their own kids from knowing. I tell her to put her issues in an email and send them to me. I'll respond then we can have a conversation about what we can not resolve. Sometimes we can't so we have to agree to disagee and move on.
I remember wanting "P.F. Flyers" but having to settle for something that was perceived to be of lesser quality.
There are somethings kids do not need to hear though. Matters of maritial disputes, they don't need to know. My Mom and Dad are both on their 3rd marriages. Add in the ex spouces and the group really grows. I grew up with constant yelling in the house. I developed a thick skin and can laugh, it took a long time though. As an adult, husband and parent, I shield my kids from the yelling and discourse in my home. Sure we have an occasional spat, but I don't raise my voice to my wife, and walk away when she does to me. I'm not listening to it, and don't want my kids to hear it.
