We buy things we don't need with money we don't have to impress people we don't like.
I understand the meaning of this sentence, but its structure confuse me because I am not a native speaker.
I know 'we don't need' describe 'things', so the first 'we' and the second 'we' can merge into one sentence, We needn't buy things with money.
but the remaining part I don't know how to deal with.
