don't get it

I think I am a subtle person yet I don't exactly understand subtly.

I think I carry with myself some elements of Chinese subtly but I don't understand when it's coming from someone else, especially from fellow Chinese. I guess they are on another level of subtlety.

This thought came about with me not really understanding if my landlord is leaving food out there for me or not and why I don't see much food left for me recently. And has stopped asking me to join them for dinner. I don't really know why. She used to ask me to join them.
