Translation of grim in Spanish

You can always write me and we can learn together any language you want. How long you have taken classes? Was it only at night or on weekends? Makes me wonder how someone can be so fluent in Spanish.
I'm quite tired too by now. So, if it doesn't work just drop me an email and I'll see it first thing in the morning. I wanted to add new words to the dictionary however the other issues kept me more busy than I have imagined.
I hope that we can teach each other a few things. I work as a nurse here in Boston, and it gives me a lot of joy and comfort because I like to help other people. It is a job that takes a lot of effort.
