Neil Gaiman in his book "The Truth Is a Cave in the Black Mountains" writes (this is a character speaking):
“And here was I, repaying ill with good, for I made you food and a fire. I am a hard man to lose, Calum MacInnes, and it ill becomes a guide to do as you did today. Now, take your dirk from my throat and let me sleep.”
What does this exactly mean: "I am a hard man to lose, Calum MacInnes, and it ill becomes a guide to do as you did today." - could you please rewrite it in simpler terms? It would be very helpful if you also could re-interpret completely 1st and 2nd sentences.
