Oh, that pendant, it was a gift from your MOTHER that you've worn all the way through the LOCKDOWN, she says that the SPIRITS will protect you from the DISEASE.
It was certainly strange coming from her, since shes an ATHEIST, it also seemed a little... Desperate?
Anyhow, you decided to keep it around and actually wear it, probably to ONE-UP her by unexpectedly following her desires, however, it has grown on you since then, so you're not wearing it for any silly reasons anymore.
