Religious moment

Regardless of our religious believes,
all dental students pray together in front of the Xray developing machine during endo clinics
5 mins of silence and faith
u cannot continue working, u cannot do anything, u just pray

and hope that after 5 mins when the tiny black thing comes out; there's no underexposure, overexposure, superimposition, elongation, cone cut, underfill, overfill......or missed the tooth altogether......
