dear mary,

thank you for your letter. you asked me to tell you about my trip to st.petersburg in summer. i went there with my family. we stayed in a nice hotel in the city centre. luckily the weather was fine and we had long walks around the city.

we did a lot of sightseeing. we visited hermitage and russian museum, because my mother is fond of arts. personally i found the ship 'avrora' the most exciting place. i had read much about it and was happy to see it with my own eyes. the city impressed me really!

well, i must go now. my mom wants me to help her.

write back soon.

best wishes,
