I can't undo
and I can't fix
it doesn't matter though
i'm done with it

i've moved on
now it's just my past
I'll stay strong
even if I come in last

Cause why should I care what they think
they're just here to hate me
and you know what i'd say if you asked me
i'd say that they are faking

No. No, I don't think they're faking.

First off, the 'past' and 'come in last' rhyme is ridiculously nonsensical and forced.

Otherwise, this is just a rapid-fire spewing of used-up breakup song lines.

Ughh what else rhymes with past? Mast, Fast, cast. I guess she could always talk about breaking bones.
