Getting from my townhouse to the nearest shopping mall usually takes me no more than 20 minutes. I can walk there either along Pushkin Street, which is the shortest way, or I can also take another way down Chaikovskogo street, that's a bit longer but also a safer way. More often than not I choose to go along Chaikovskogo street because I don't have to cross a lot of roads on my way to the mall.
So, when I step down the porch of my townhouse I get in Petrovskogo street and I start walking down it to the first intersection between Petrovskogo street and Pavlov street, then I turn right at the corner of Petrovskogo street and get right in Chaikovskogo street. Then I start going down this street. This street is not one that goes down straight ahead, following it I have to turn left near the Central Bank building and cross the road at the crosswalk. After that, I proceed to go straight to the florist's and bakery located close to each other on the same side of the street. I take a left turn behind the bakery, past the metro station and get to the underground pedestrian crossing. I walk down the steps and walk straight through it. I come out of it on the other side of the road right in front of the shopping mall.
