I found a vape pen in my 18-yo son's room. I've made it clear to him that I don't approve, yet he is of legal age. Should I punish him? We haven't talked about adding each other on Facebook or any other social media. He's gone for a few days and I already miss him. I found him on Facebook but I haven't added him yet or anything. I feel like telling him that I miss him. Do you think I should?
