My sister has a 15 year old son, he's got a girlfriend the same age, they've been together about 6 months.
She thinks it's ok for him to stay round at her house in the same bed. Also her parents go camping most weekends, about 20 mins drive away from where they live. She also lets him stay over Friday to Sunday when the parents are away.
We've had a little argument about this, well disagreement. I've told her I don't think she should be letting this happen at 15 year old, she thinks it's fine and I need to "get a grip and chill out".
Just after other people's opinions. What do you think, am I right or is she?
