>>1395130>the only way for "just" to be literal if that's how you think about it is to have the event happen within the shortest timeThat's actually the difference. In the case of "just", "literally" acts as an intensifier (which you seem to not like, but too bad), but also to clarify that it's objectively "just" and not just "just WRT the speaker's expectations".
>I just bought this car but the handbrake snapped- speaker bought the car recently enough that it shouldn't be expected, but the brake failed anyway
>I literally just bought this car and the handbrake snapped- the handbrake came off as the speaker was driving the car home off the forecourt
Note also and/but: "but" because it's counter to the speaker's expectations; "and" because the two events happen simultaneously
