A school is supposed to be open during business hours and not start way earlier in the morning than normal business hours. This is totally ludicrous. The earliest Grey's high-school should start is at 8.20am and the primary school at 8am.
These days parents work the hardest they've ever worked, merely to put food on the table and now the school hours are as ridiculous as a person can find. Overseas school start no earlier than 8am, but most 8.30am or 9am.
