I'm always listenING to rock and pop. I like to play 'at' AN upright piano. . 'My best school's lessons' (napisz to inaczej, bo z tgo ja czytam, ze chodzisz do paru szkol i masz jakas 'best' i w niej..cos tam...ale chyba tego nie masz na mysli...tutaj My best lessons at school...) are English, music and history.
I think my English is good, but sometimes, when I'm 'stress' (stress jest rzeczownki, tutaj czasownik czas przeszly STRESSED) I don't understand anything. My friends say that 'i'm' (I zawsze piszemy duza litera) crazy, nice, cheerful and bold.
'I too think so.' (nie, - tutaj I think so too. -ja tez tak mysle)
If you 'wan't' (nie, tutaj uzylas zlej formy, tutaj 'want-chce' to talk with me please write.
