Hi,
My vote is that it is not a control thing at all.
I'm 45 and never liked fireworks, actually terrified me as a child. My now 13yr old daughter felt the same. The joy of the colors is lost in the tension of waiting for the noise. We hate any loud startling noise. If the older kids wanted to see the town fireworks display, I would gladly stay home with my daughter. The book "Highly Sensitive Child" helped me understand myself and my daughter, we're just wired a bit differently. :)
When our children were little I would sit inside the house with the kids while daddy lit sparklers (placed into the yard) and low and no noise fireworks. We had to assure our daughter that the display would not make noise and had her wear headphones (with no music, the kind for yard work). We started with sparklers and after each display we would check in with her. She slowly became more and more comfortable.
Surprisingly, for the last few years my daughter and husband have put on their own fireworks show. When they go to the fireworks dealer tent in the parking lot of Meijer, they ask for all the no noise and low noise displays. They take about 40 mins talking with the dealer to make sure they know what they are buying. My daughter feels much better knowing what each one will do before they light it. She even explains it to everyone watching so that we won't be tense. :)
Best wishes.
