There is no obvious harm,
And not every hurtful person has it written on his forehead that he is hurtful. Poisonous words are hurtful, lack of appreciation is hurtful, underestimating the anger of others is hurtful, abandonment is hurtful, lying is hurtful, taking advantage of the kindness of the one who gave you safety is hurtful,
Harm
has many forms,
and its effects are not necessarily visible on the features of those in front of us.
