Being an only child brings many benefits (dlaczego tutaj nie dalas przecinka?) but many 'drawbags' (zle slowo) too. 'Are' (zle slowo) 'haveing' (ortog) no siblings, (brak przedimka) blessing or (przedimek) 'course' (zle slowo)?
On the one hand if you are (przedimek) only child your parents pay more attention to you. There are also no problems 'witch' (widze czarownice or babe jage tutaj) 'argeuing' (ortog) or fights. You don't have to share your things 'witch' (ale wiedzma, znowu sie pokazuje..) any other person.
Being (przedimek) only child means getting a larger share of the family's income.
On the other hand you have to rely on your parents 'in' (zle slowo - tutaj 'w ciagu') bad days. Sometimes it's better to have someone closer than (cos brak) parents, someone who will understand you better than them. 'You have to play 'witch' (znowu nas przesladuje, ta baba jaga) yourself', (w jez. ang. 'to co napisalas to znaczy uprawiac to, co nie jest uznawane za cos o czym mozna rozmawiac w dobrym towarzystwie, musis to inaczej ujac) 'make' (calkowicie zle slowo) housework alone. Loneliness is 'handsome' (dla mnie tylko mezczyzni, i to tylko niektorzy sa handsome, ale to jest zle slowo), especially if you have to clean up the house.
In conclusion it seems THAT (prosze nie zapominac o tym THAT) being an only child is (przedimek) blessing, but only in theory. 'Mainly by getting more attention and physical benefits' (to wg mnie nie jest zdaniem, prosze dolaczyc go do poprzedniego). In reality it means boring loneliness 'to'(niepotrzebne slowo) 'the' (niepotrzebne slowo) adulthood, (brakuje slowa) even later it doesn't bring anything good. In my opinion 'haveing' (ortog) no siblings is a 'course' (zle slowo). 'Its' (napisz to poprawnie, tu maja byc 2 slowa IT IS) important to have someone closer than your parents. If you are (przedimek) only child, it's good to have at least (przedimek) best friend, which will support you in the 'bad' (poszukaj inne slowo) days.
Co ty robisz z tymi przedimkami (a, an, the). Nie wiesz kiedy je uzywac, i dlatego, prosze sobie przypomniec ich zasady w zdaniu.
