I’ve had to learn the hard way that a word can mean something quite dissimilar for two people. Sometimes it’s based on assumptions or misunderstandings. Sometimes, on deliberate deception.
Either way, one person can be deeply injured by the outcome.
Take “I love you” as an example.
A used car is in “perfect condition.”
“I’ll be right there.”
In the hippie era, we had a raft of phrases that glossed over differences – “Hey, I’m cool with that,” “Don’t hassle me,” “I dig,” “Chill out.” Meaning?
It comes up especially with “God” or even “peace.”
There are plenty of other examples, some of them keeping lawyers in business.
What’s one from your own experience?

“There are plenty of other examples, some of them keeping lawyers in business.”
As for examples? A lifetime of them. 😃😃😃
Got me laughing aloud on that one.
