But hope isn't always sunshine and unicorns. "I hope you're happy" is often used to express displeasure with someone or something and "I hope s/he rots in Hell" is probably one of the more common "hopes".
Yeah, Boomer, but they say it with feeling, whether to say I hope you're happy
or I hope s/he rots in hell
. Thoughts are things, people really do feel their impact, whether or not anything is said.
