why don't you / why didn't youThis is the beginning of an informal question meaning “why don't you...” or, with a past-tense verb, “why didn't you...”. Here, меня means “me” with verbs such as подождать (“to wait for”). The pronoun may change to мне with verbs such as доверять (“to trust”), сказать (“to tell”), and перезвонить (“to call back”).
