Can someone be charged with harassment for a one time offense and it was not said directly to them?

Yes, someone can be charged with harassment for a one-time offense, even if it was not directed at them personally. Harassment laws vary by jurisdiction, but typically they encompass behaviors that create a hostile environment or cause distress to an individual, regardless of direct communication. If the behavior meets the legal criteria for harassment, such as being threatening or intimidating in nature, charges may be pursued.
