I'm not going to participate in a lock down drill
Why don't you want to participate in the drill?
Those drills are stupid and childlike.
It is okay to find them annoying, but they are important for everybody's safety. You could make things more dangerous -- everybody should know what the others or doing and how they'll respond during an emergency.
Now you're scaring me, I didn't think of it that way. I've changed my mind.
Glad to hear you feel that way! Everyone will be safer.
