News alert: Paris Hilton has realized she’s an adult.

“Now I realize that I’m an adult and I’m running a huge company and I’m in love,” she recently told People. “I’m in a great relationship. I have my family. I’m just excited for life.”

Prepositions describe relationships, so we must be careful to choose a preposition that accurately conveys the relationship. We use “excited for” when we share someone’s happiness. (I’m excited for Sarah’s wedding.) To be excited for life suggests Paris sees general promise for life, as an separate identity (or even a person). Life, I see great things for you. What she means to say is, “I’m excited about life.” Also OK: “I’m excited by life.” These prepositions suggest that it is HER life that excites her.

Then again, Paris may be using all her rhetorical powers to describe the songs she and her boy toy, Benji, have written.

“The music is really fun,” she told People. “It’s really just happy and fun dance music.”

What an insightful description of the music: fun, happy, fun. Really, really.
