What actions constitute “trespassing”?

Trespassing is defined as entering someone else's property without the owner's permission. In the context of the options provided, entering private property without permission clearly aligns with the legal definition of trespassing. This action disregards the property owner's rights and boundaries, making it a prohibited act under trespass laws.

The other choices involve scenarios that do not meet the criteria for trespassing. Visiting friends after hours might be acceptable if the friends reside on the property and have given permission. Using public areas for gatherings typically falls within the rights of individuals to assemble in places designated for public use. Parking in public spaces is generally lawful, provided that the vehicle complies with applicable parking regulations and does not infringe on private property rights. Thus, the correct choice accurately highlights the behavior that constitutes trespassing.
