Reading over the psychic's shoulder was weird. Her interpretations of the cards were either too simple or they really deviated from the textbook meaning. This was true on the four of cups. This is typically of card of being too sure of oneself and indicates a place of lazy danger. It is not typically a 'friendship, love, nature' card.
The caveat here is that there is not really a thing such as a typical reading. While one does have the textbook to fall back on (traditional meanings), the cards can easily take on meanings different from typical, especially when they care combined with other cards to tell a story. With that said, that four of cups card coulda/shoulda been read different to provide a warning instead of reassurance. BUT, the grand lady they used was a professional psychic and I'm just an engineer, so what do I know? (smile).
