I think it's you, not he, who is acting like a 2 year old. Why on earth should your dad want to go paint balling, especially when he's feeling very miserable about being made redundant. He needs time to wallow and to adjust. Just be there quietly in the background for him. I remember only too well what Life was like for my family when my dad was made redundant. He didn't have work for 18months. His self respect hit rock bottom and my mum, after several months of being patient, eventually flipped. It's a very difficult time for him and will be for the whole family, if he doesn't find something else soon. Don't add to his problems by seemingly brushing them aside and expecting him to do crazy things!
