мой дедушка живет в небольшом городе.

last year my family and i went to the seaside. we spent two weeks in the crimea. we had the wonderful time at the seaside. most of all i liked the discos in the evenings. the music was fantastic. we danced a lot and ate ice cream in the cafe. i enjoyed the rest at the seaside very much. it was only a pity that two weeks were spent very quickly and we had to go home. i hope to go there again the following summer.
