Everyday I pick DS (4) up from his class and then make my way round to nursery to pick up DD2 (3).
So today I do that as normal, leave DS' classroom and then turn round to find DD2 stood in a crowd of people absolutely bawling her eyes out. Either her nursery have let her out without checking I am there or she snuck out (despite two teachers being on the door and gate). They told me they didn't call her name but she tells me they did and she isn't the type to run off.
There are plenty of cars driving around in the part where I found her or she could have easily started walking out onto the road where I usually park my own vehicle.
Do I just accept their apology or do I need to have a word with the head?
