Something as simple as the words "You're next" can have quite the different meaning depending on which place they're being said. Wedding? Okay. Funeral?..... Nah, I'm fine.

I love you, Sofia. Marry me.
Yeah, some details can really change the meaning of a simple phrase. That includes time, place, how it's said, and who says it. For example, "you're next" is not very pleasant to hear if it's being said by a serial killer. Also, "let's do it by parts" is generally understood as harmless, but it acquires a whole different dimension if it's being said by Jack, the Ripper. :P
Yep. The time and place are now. You might have to go another lifetime before you get another chance.
