In the meantime I am listening to some Spanish CDs. They are intended for the car, but no one can tell you when to listen to it, how many times and how often. Please understand that I work a lot.
I went back to the busterminal and dressed for the ride. That means I put on long pants and my hiking boots. Friends have warned me about freezing conditions during bus rides because of airconditioning.
As soon as I went to bed, incredibly loud music starting playing from right beneath my room. The music was so loud that I could not fall asleep despite my jet lag and despite being extremely tired.
