It means that, well, letâs say you forgot to do homework and itâs due today. In that situation, it would be an enemy, because you really need to do it but you canât, âcause you have to get ready. But maybe, it starts to rain really hard. You may have time to do it, and time would be an ally.
Time depends on you because if you do something you need to at first, itâll be completed. But if you donât, youâll face the consequences.
Hope this helps! Iâm kind of bad of explaining things so hopefully this makes sense.
