everyone has different values but i`m sure the most important value is a family. i think a happy family is the biggest treasure because these people are always ready to support you, to give a piece of advice and just to hug you after a hard day.

my family is not big. i have a mother helena, a father ihor, and my younger brother andrew. i admire my parents. they are very smart and hard-working people. my mom is such a beautiful woman! she is tall and has very long wavy dark hair. she is an architect and she is really professional in this sphere. she taught me how to cook a lot of tasty dishes, sew, to do laundry, etc. i enjoy the time we spend together because i always learn something new.

my dad has a unique personality and he is an amazing interlocutor and parent. he always pays attention to me and my brother, makes little trips into the forest or to the river almost every weekend and has a great sense of humor. he is a teacher of math and physics in high school.

my little brother andrew is still a baby. he is always full of energy. i like to watch how he grows up and always help him to discover this world.

we are very friendly and i think i`m incredibly lucky to be a child in this family! my parents spend a lot of time with me and andrew. every friday as soon as my dad gets home after work we watch a film together and eat some sweets. on holidays we often go somewhere. for example, last summer holidays we went to paris and it was awesome! i even got inspired to learn the french language because it`s so beautiful.

if a conflict appears mom always tries not to shout and unleash it with words. i`m incredibly grateful for such an amazing happy family!

but sometimes it happens that there are some problems in families. i think in such situations it's important not to forget that a family can be really happy if all members are working on it. you must care about your parents and siblings, support them and help. i understand that sometimes it`s not that easy but i`m sure that in the future you`ll create a wonderful family by yourself!
