How to get lost in Lima

I got lost today, badly! I went out early to fulfill my mission of getting to work by foot, but I ended up at the National Stadium. I was later told that the area was not nice, but I never felt unsafe and there were always lots of people walking too. This incident made me test the Metropolitano, which works in the same way as the Transmilenio in Bogota. It was quite an experience since at 8:30AM it is packed. By packed I mean that there was people pushing more people from the door to fit in and I never saw anybody wait for the next one, so use your imagination! It was very fast though and another checkmark on my things to do in the city. I also went alone for lunch to this restaurant called Susy Wong. For about $4.60 I got an entree with potatoes and chicken, rice, fish with mushroom sauce, vanilla pudding and passion fruit juice... great deal! They even give you a little piece of paper with the things available for next day to plan, which is a good idea. In the afternoon I drew a little map with every street that I needed to take to arrive home and it worked perfectly. It took me about 45 minutes to do it, but with the mildly cold weather it is a pleasure to do it. One of my roommates made some delicious brownies for her boyfriend and just for the price of cleaning the dishes I was able to enjoy one that was just out of the oven (delicious!). I will have another night without covers since they haven't brought them yet, so I am covered from head to toe. I only have one complaint so far... why do people have to beep their horn all the time even in the middle of a huge traffic jam or when there is no traffic like midnight? I am next to a big intersection, so even now I can hear them.
