And it blows my mind that people don’t understand the English language and use analogies that don’t apply. Here is one definition of harm, feel free to look up others that may prove your point. “harm. Harm is a deliberate injury or damage to someone or something. A playground bully is a mean kid who causes harm to other kids. Harmis both a noun and a verb — when you inflict harm on your brother, you harm him. ... The Old English root word is hearm, which means "hurt" and "pain," but also "evil" and "insult."Now, as I read it, the only possible “harm” here, is the possiblity that his truck was “harmed” by the “illegals”. Was his truck “harmed”?
You have chosen a very narrow definition of the word harm. You left out a lot that applies:
-actual or potential ill effect or danger.
Possible exposure to covid is definitely potential danger. Possible damage to the vehicle is harm.
-have an adverse effect on.
They wasted his time and insulted him. Those are adverse effects. I don't know how much your time is worth, but mine isn't cheap.
Then there is the legal version of harm:
-any injury, loss or damage. It can also be any material or tangible detriment.
As discussed above, he lost time. In addition, he lost use of his vehicle. If someone wants to use a vehicle that belongs to someone else, they generally have to pay for that privilege, so that is money and wear that was lost.
So, sure, by your definition, there was no harm. But by generally accepted definitions, the OP has obviously suffered harm.
