Excerpt:
Se han perdido las llaves
“The keys have lost themselves.” I didn’t lose the keys. They did it to themselves.
La planta que me diste se me ha muerto.
“The plant you gave me has died on me.” I didn’t kill it! And it didn’t just die, it died for me.
I will add that in the last year or so, I have taken a cue from Spanish and French and started saying "No problem" most of the time when thanked. I think the phrase "You're welcome" reinforces a sense of social obligation that makes me uncomfortable -- a sense of indebtedness. "De rien" or "de nada" ("it's nothing") acknowledges the "thank you" without conveying a sense of "now you owe me". So I have begun trying to find an English version of conveying that idea/feeling/social paradigm. "No problem" is the reply I find myself using most often.
