I am probably a more lax parent, but am lucky I have a sensible, mostly responsible teenager. But age you would leave overnight is something I am struggling with.
DD as I say is sensible and mostly responsible she can make a meal, run the washing machine, can mostly be relied upon to fed the pets ( definitely if alone). She can travel well on public transport to various locations.
Home is in a 'naice' area down a lane, has electric gates, downstairs burglar alarm that can be on when asleep, village shop and bus stop are 5 mins walk away, she would have 4 cats and a dog for company, I would allow a girlfriend to stay with her, but not her boyfriend ( geographically distant homes so he would be reliant on his mum for transport).
I am considering it for early December DP has his work Xmas do, we would need to stay a single night in London would leave about 3pm be back about midday the next day. We would have a couple of drinks, but are not heavy drinkers. She would be almost 15 in fact if she had been born according to original plan she would be 15 so very close. She happily babysits other people's children. She is trusted at school which is 6months to 18 years and regularly works with reception, nursery and year 1 pupils on drama projects as she is a scholar.
My heart says she will be fine and cope well probably lounging around watching TV and doing homework. I just wonder what others think. I do have 4 months to make alternative arrangements if necessary, but I do believe in gradually creating independence.
