Lyrics:
oh how time flies,
before our very eyes,
he has become a true gentleman,

our son has found his place,
with courage he will face,
any enemy to protect equestria,

he rose to the captain of the guard,
with passion in his eyes,
now he is with his wife and became a prince,
of an empire fair and wise,

oh how time flies,
before our very eyes,
she has become a young woman,

our little girl keeps growing,
and soon we will be knowing,
that we have to let her go,

from the academy, to the castle,
to the town, and upon the land,
she has faced down any obstacle,
with her friends she will make a stand,

we knew that they were special,
but didn’t know they’d go this far,
we couldn’t be happier,
we are proud of who they are,

oh how time flies,
before our very eyes,
i wish there was one more day,

where we can hear them say,
hey mom and dad, let’s go play,
before the moon starts to rise,

the dye has been cast,
it wasn’t meant to last,
oh how time flies
