It’s generally an acceptable thing to express beliefs and practice certain things you hold important, even when in the workplace. So, it may seem acceptable to hold a small ceremony when something passes – but this usually refers to a human being. It can be a little too much when someone acts like a crushed bug is the end of the world.
This can be a laughable experience if you have the right sense of humor. People who see something small scurry across the floor of their office will generally try to dispose of it with whatever means necessary. You should probably make sure you don’t work with a bug-lover, or at least don’t let them see it after you do it!
