Hi Jane!
I know you are coming to Moscow, and to make you feel at ease, I want to invite you
to stay with us.
I think the family is the most important thing for every person. The family are
people who always love you, support you and help you. People say: “No Man Is
an Island.” For me it is impossible to live without my family.
My family is rather large. It is very friendly and united. I have parents, an elder
brother and grandparents. We all get on with each other very well. We spend
a lot of time together.
My father’s name is Konstantin Alexeevich. He is a plastic surgeon; he helps people
become more beautiful. He is a real professional. He is considerate, hard-working
and intelligent.
My mother’s name is Liudmila Mikhailovna. She is an engineer, but she does a lot of work
about the house. She keeps the house and looks aft er us. She cooks very well. Our mother
is very kind but strict with us. She always checks how we do our homework. Mother
arranges our free time, so that we cannot just fool around. She is fond of reading.
My brother Alexei is 22 years old. He is a student at the Medical Faculty in Tver State
Medical Academy. He wants to become a good surgeon like our father. He is also a member
of the local theatre club. He oft en plays main parts in the plays. He comes home almost every
weekend.
My grandfather is a historian and grandmother is a linguist. They give lectures
in universities and write scientifi c books.
I have my duties about the house. I go shopping and clean the rooms. I like my home to be
clean and tidy. I think home is the nicest place. There is no place bett er than home and there
are no people more dear than your relatives.
I am looking forward to gett ing your reply
Best regards
Alex
