“When you grow older a dreadful, horrible sensation will come over you. It's called loneliness, and you think you know what it is now, but you don't. Here is a list of the symptoms, and don't worry - loneliness is the most universal sensation on the planet. Just remember one fact - loneliness will pass. You will survive and you will be a better human for it.”

“Loneliness is like starvation: you don't realize how hungry you are until you begin to eat.”

“If you don't need it, then
it is useless to be compassionate.
If it's important then
it will probably be followed with pain.
Loneliness that you feel with someone is worse
than one you feel
alone.”

“There is in certain living souls a quality of loneliness unspeakable, so great it must be shared as company is shared by lesser beings. Such a loneliness is mine; so know by this that in immensity there is one lonelier than you.”

“Perhaps loneliness had nothing to do with place or circumstance; perhaps it was in you; yourself. Perhaps, wherever you were, you took your little circle of loneliness with you…”

“What is it?' Stephanie whispered.
'That, my dear Valkyrie, is what we call a monster.'
She looked at Skulduggery. 'You don't know what it is, do you?'
'I told you what it is, it's a horrible monster. Now shut up before it comes over here and eats us.”

“Real loneliness is not necessarily limited to when you are alone.”

“What do you care? You always liked loneliness better than you liked people. No offence — liking yourself’s the beginning of all love.”

“Over time, loneliness gets inside you and doesn't go away.”

“If you're calling me up just to chat, mundane, you must be lonelier than I thought.”
