I had not been around any Spanish since the middle of December so the first day was difficult for me. I couldn't talk with Hermana Arevalo, and Hermana Perez did not arrive until later that night, so I felt awkward most of the day. However, since that first day, being around it almost all of the time has helped me "pick it back up" very quickly. I can understand most of what is said. Talking is much more difficult.
I practice by constantly reading and writing in Spanish. All of our classes are in Spanish. I also received a packet of books in Spanish, so I can read the scriptures and Preach My Gospel in the language.
Right now, my brain in confused because it doesn't know whether to think in Spanish or English! It is a mess. It gives me a headache! :P
