Partners

Now here is a word that completely confounds me. I cannot tell you how many people choose to introduce me to someone with, "This is my partner." And my brain goes:

Is it a business partner?

Is it a sexual partner?

Is it a life partner?

Is it a partner in a club or association?

Is it a partner in crime?

Usually the conversation will shed some light eventually. Bur for a while, I'm cracking myself up imagining different scenarios.
