Go to school and find that...

Eh !? Today is still holiday?? I was just feeling strange that there weren't too many cars at the car park when I arrive at LI. When I was about to 'open ' the door (surely it's impossible), I saw the paper on the pane printed that '3/18~3/22 Easter Holiday.' Shocking...I'm literally wasting my time. Who's that told me that we had 4-day holidays??
