Sprawdzi mi ktoś poprawność gramatyczną tego tekstu? Dear Santa Claus, Currently I am spending boring time in this winter's evening, so I decided to write letter to you. I would like to short introduce myself. My name is Dominika. I live in Poznań with my family. I love spending my free time with my friends. My hobby is art. I almost all the time draw something (by the way I hope you would like how I bedecked this letter around the text). Even that I am a seventeen year-old girl I still believe in you. I always appreciate your work in the most special time of the year - Christmas. Then people could meet their loved ones and spend some time together, they enjoy the festive mood. I love Christmas time as people are nice to one another and try to forget about stresses of everyday life. I can't imagine this period without you, Santa. I would like to mention that I was very polite this year. I tried to be kind and helpful to others. I got also good marks in school and fulfilled my responsibilities. As you know I am not little girl anymore, so I won't ask you to give me some new toys. I don't want to also get a definite material gift from you, but I would like to ask you about few things which can make me happy in my teenage life. I wish that: - Everyday wake up to school will be easier than now - Make that math (I really don't like this school subject) will be more bright - Get to know only good people - Less arguments with loved ones - More successes in developing my passion - good luck in New Year 2017 I hope that you can make my nomaterial dreams come true. Thank you in advance and best regards for you, your wife and the reindeers of yours.
