Nature is sensitive. When someone dismisses an event as being insignificant and of no impact, Nature may regard the same incidence in a different way. 

One is liable for any exposure of one's body, for any attendance at any scene, for being there and being seen or sensed in any way. This falls back to the stipulation for yogis to be in isolation. When full isolation is not possible, then partial or the least possible exposure should be a yogi's attitude.
