It's a phrase that conveys a sense of:
* Simplicity: It suggests a life that is small and manageable, perhaps focused on the basic essentials.
* Intimacy: It implies a personal and private world, not meant for everyone.
* Positivity: Though small, it's "my" life, suggesting ownership and perhaps even a sense of contentment.
It can be used in different contexts, such as:
* Expressing contentment: "I'm happy with ma petite vie, simple but fulfilling."
* Describing a limited scope: "I'm not a big traveler, I prefer ma petite vie at home."
* Adding a touch of endearment: "My little life, my little world, that's where I belong."
Ultimately, the exact meaning depends on the context and the speaker's intention.
