lock-"in"

Today started as any normal day but as first period started, someone came on the P.A. saying we are going into a lock-in. We all huddled up in the corner asuming it was a shooter but were then notified that there was a bomb theat. We were told to leave EVERYTHING at our desks and go out to the field. I even left my phone not knowing that we wouldn't be going back to the class. We then proceded to walk quietly to the field and sit in a designated spot for our class, from there we spent 2 and a half hours in the field trying to keep ourselves entertained. On top of that it was freezing cold raining and I didn't bring any warm clothes. After a painful 2.5hrs we went onto a bus bringing us to a place call Foam X, an abondoned foam factory that they use as a warehouse now. We then waited another 30m for our group to be called and finally go home. This started at around 9:30am and we got out at 1pm.
