Our teenage son has stolen money from the family safe?

It is important to address this situation with your son in a calm and non-confrontational manner. Start by having a conversation with him to try and understand the reasons behind his behavior and to express your disappointment and concern. It may be helpful to set clear boundaries and consequences for future behavior, and also to work with him to come up with a plan to pay back the money that was taken. It may also be a good idea to seek the help of a professional therapist or counselor to work through any underlying issues that may have contributed to this behavior.
