My first week there I was petrified to leave the apt. Julius had taken Monday and Tuesday off (I flew in on Monday), but then I was on my own. My friend Michael who lives in North Beach came over on Thursday to get me and take me around. We were all over the place and I still had no idea where the heck I was. At the end of the day Michael put me on a bus to go back to Julius' apt. and I was so lost it wasn't even funny. I had my MUNI map, but when you don't really know where you live on the map, it's not all that helpful. Someone on the bus helped me and got me off the bus in the right place and told me what bus to wait for. I was scared out of my mind as it was dark and I had no idea where I was or where I was going.
I'm glad you'll have Eric to get lost with. It's much easier when you're not alone.
