Dear (imię przyjaciela)
I'm glad to hear you. My school is modern too, but we don't have laboratory. Science is interesing for me, because we do a lot of interesting experiments. My favourite subject is biology and P.E. We play a lot and in next month we will have competition. I hope that couch will choose me to play in school team. Generally i'm sure he will :) Tell me more about your school and are you have any friends?
Best Regards, (twoje imię)
