On Sat night when the Biden's and Harris's were in front of the lectern waving to the crowd did anyone else notice the reaction of Mr. Harris and Joe Biden when the pop sound from the first confetti bomb went off?

They jumped and I have to admit, I thought a gunshot had been fired and even more scary, with the climate created by the Trumpies, my first impression was a valid one.     

I'm surprised I haven't heard any comment about this.
