Confused on how to confront this
So my daughter recently graduated from high school and her father who is not really involved texted her to let her know some family members had dropped off cards for her at her grandparents home. For context father lives with parents and has had on and off drug/ alcohol addictions. Anyway we go to pick up cards and one was sealed with card and money inside the other was never sealed just tucked in but no money. How do I go about asking family member that we don’t really have a relationship with if there was money without sounding greedy because I think he may have stole it?
