Why are you comparing boredom and loneliness? It’s kind of like apples and oranges.

Boredom isn’t sad. Being bored is sitting at a staff meeting having to listen to some irrelevant presentation and not being allowed to leave. It’s not sad, just annoying.

Loneliness is a sad feeling. Example of loneliness is losing one’s spouse and being in empty house longing for his presence (I’ve never lost a spouse but my daughter is a widow and I remember first year after my son in law she used to say she felt loneliness, snd certainly wasn’t bored or isolated, she is a social butterfly)
