why would someone tell me that my guardian angel works overtime?

Someone might tell you your guardian angel is “working overtime” to suggest you’re facing a particularly challenging time or situation, and your guardian angel is providing extra support and guidance. It could also be a way of expressing belief that someone or something is watching over you and helping you through difficulties.
Here’s a more detailed breakdown:

Extra Support in Difficult Times:
The phrase “working overtime” implies that your guardian angel is being particularly active and attentive, perhaps providing more guidance or protection than usual due to a difficult period in your life.
Belief in Divine Protection:
It could also be a way of expressing faith in a higher power or a belief that you are under divine protection. The “guardian angel” is a metaphor for this protection, and the “overtime” suggests a heightened sense of that protection.

Metaphor for Spiritual Guidance:
Some people believe in the concept of guardian angels as spiritual guides, and the “working overtime” metaphor could suggest that your guide is particularly active in offering advice and support
