My 15 year old daughter revises for her GCSE's each evening at the local library because she says it's perfectly quiet and she feels 'in the zone'. She shares a bedroom with her 11 year old sister and while they get on ok, I understand she needs a nice big desk space to herself, which is another reason she likes it. It's been working well until tonight when a staff member approached and asked her age. He then told her to leave as only over 16's are allowed in after 7pm. She messaged me asking to be collected early (we arranged 8.30 as a pick up time and I message her when I'm in the car park). Luckily we live a 10 minute drive, but she was tearfully stood outside alone in the car park when I arrived. I know she's not been causing problems as it's not in her nature, and I have an old school friend who works there and said only last weekend when we passed each other that it was lovely to see her each evening busy working and reading. She never mentioned a 7pm cut off, but she might think my daughter is over 16 as she looks and behaves quite maturely. AIBU to complain and ask them to let her have the extra 90 mins each evening? She's 16 in July but her exams will be over by then.
