What's the occasion?

This morning Jeffrey and I noticed lots of young adults 20's early 30's congregating at the mall. I did not know what the occasion was/is as we went to work at the Area office and MTC Dental Clinic. We only worked till noon and then came home. I have to admit I was pooped even though it was only 6 hours instead of 8 or so. I napped for just a bit and then studied my Primary lesson. Went grocery shopping and found a nice young man to push all my groceries back to the apartment. I love the service here.
Tonight the fireworks went off! Why?


I love the fireworks going off, I just wish I knew why. This was in a mall a ways away so I could actually photograph them.  The ones in our mall are too close and the camera picks up all the particles and dust smoke.  What kind of events are fireworks worthy?
