Changee between friends

People argue [[change]] is what you have to
do as you get older, but in {reality} you change
because you {want} to not because you have to
but [[sometimes]] you change for the wrong
reasons so look back on what you {left} behind
for what you have {now} and decided what
will be there for when the [[now]] screws you
over and you don't have what you {left} behind to
[[help you through]]
