Would be really grateful for your opinions on this: an acquaintance of mind told me he and his wife left their 14 year old son alone for a week in their house over the summer holidays. I was completely shocked (I wouldn't leave mine for a night alone), but he just said they were quite chilled about things like that. They live in a village with many friends nearby. Am I completely old-fashioned? Or is this - as I thought but didn't actually say - incredibly reckless behaviour? I ask because I almost feel like I should say something to him, but I don't want to come across as a busy-body if this is normal these days.
