Well, yesterday, my DD & I had a conversation about how Oxford University students have voted to do jazz hands instead of clapping at all their events because clapping can be triggering.
So I guess you can add clapping.
And, for what it's worth, I saw the black jack o'lanterns as painted & decorated to look like skeletons.
I have a set of black flamingos in my yard right now w/ white skeletons painted on them to look like skeleton flamingos & the black pumpkins w/ white faces made me think of my skeleton flamingos... because it's Halloween.
