This happened just before my '10 ' (tu brak 'th' bo masz na mysli dzisiate a nie dziesiec) birthday. (At the time) I was in primary school. First I helped my mother (z czym? z shopping, cleaning?). We got down to prepare (brak slowa) my 'birthdays' (bez 's- wystarczy 'birthday') party together.Then as I (cos brak) cleanning my room,I suddenly 'rememberd' (ortog) that I 'didn't' (zle slowo, tutaj 'had not') doNE my homework.
I tried do my 'homework with maths' (zle, wystarczy 'maths homework') , but I kept on making mistakes.
While I was crying I suddenly saw that my cousin came inTO my room .
We found out more information in (brak przedimka) maths book together and we solved the problem .
Finally (brak przedimka) next day I went to school and I got 'five' (to fdla mnie nic nie znaczy, trzeba napisac 'top marks') with 'this' (l. mnoga - to ma sie zgadzac z exercises) exercises. First I stayed up and I had (brak przedimka) bad mood. Then I missed (przedimek) bus and I was late 'to' FOR school.
'I didn't have chillout this day' (cos dla mnie jakos nie tak, mozna...I didn't have a chilled out day) My class 'has' (zly czas) (przedimek) unexpected short test 'with' IN biology . I couldn't come up with (przedimek) solution (brak slowa) this exercise.
While I was going out (brak slowa) school I saw that my bus (brak slowa) left.
As I was 'being' (zle slowo, tutaj 'getting') near (brak slowa) my home I 'perceived' (trosze slowo nie pasuje do reszty, moze 'realised') that I 'forgott' (ortog) (brak slowa) keys.
