As a grandfather, I see an number of things we can do to stem the rise in crime.
When they are little accountability starts. If they take something that doesn't belong to them make the understand what they did and take them to confront the person or store they took the item from. When they get into conflict don't just take action because they used violence, find out what really happened. Self defence is perfectly fine in my books, if they were being a bully however, intervention is required.
Teach them respect for themselves and others, and teach them to deal with differences of opinion by listening and contributing to constructive discussion.
Teach them to participate both socially and with chores, in the family and the community.
And most importantly, be a good example.
This fall for example, I had a problem getting my crop off toward the end.
My older grandkids all came out, some took time off work, the only demand they made was they refused to take any money. The reason is I helps them out when they are a little short, or I fix vehicals that are broken down, and do a host of little stuff to help, and in turn they wanted to give something back.
I've only had one that started down a wrong road. I asked him some questions and found out what he would really like to do. My wife and I bought him a guitar, today he has his own band, three guitars and is no problem.
For far too long older folks have failed to communicate, failed to set boundries,
failed to be an example, gave the everything they want and now we wonder why we have problems. You may not always like what they say, but if you communicate you will at least know what they're up to.
