Dd1 has just started upper sixth and wants to go to University. Naturally she wants to visit some to see what they're like, but most of them require an overnight stay. - and here's the issue - she doesn't want me or any other adult going with her. She's 17 and one of the most sensible teenagers you'll ever meet. She doesn't drink (wont touch a drop - its a drug!), smoke, stay out late, party and is not interested in males unless they're a horse. I had no issues with leaving her at home on her own for 2 weeks with the dog (with 3 of my friends phone numbers - just in case). However she's a high functioning autistic and both struggles with social nuances AND is the most trusting person on the face of this planet. Yet in a year's time when she starts uni I wont be living beside her making sure all is ok. Are other parents letting their 17 year olds visit uni's and stay overnight on their own?
