Vacations in Oaxaca

I don't have classes on Fridays this semester so I come every 2 weeks or so to Oaxaca (my native city). I'm studying in Mexico City. So I took a bus on Thursday afternoon. It was supposed to get to Oaxaca at midnight but there was a lot of rain and traffic so it was delayed two and a half hours, I got soooo bored on the bus and I couldn't sleep. Well I got to Oaxaca at 2:30 am. As soon as I touched the pillow I fell asleep. Yesterday, Friday, I met a friend downtown and we went for a walk on in the city, he stayed in my house for the night and we went to bed at 1:00 am maybe so now I'm a little sleepy. Today... I don't have any plans yet.
