[English grammar: either // gramatyka angielska: either]
From the first paragraph of this week's vocabulary lesson we know that the writer doesn't depend on public transport because you can't count on it and the person added 'that my car was not very reliable, either'.
Remember that when you have two 'positive' ideas and you link them in one sentence, then you should use 'too' at the end:
Buses are always late and the trams are late, too.
However, if you have two 'negative' ideas and they are similar, then 'too' cannot be used at the end of a sentence. Look what you are supposed to use:
A) I don't like X. B) I don't like X, either.
