Wish I was... 'a-teen' again

Ah! and then you come
traipsing la la 'long
on your two high notes
and yes, an uppity bow.

Eighteen and then some
that was oh so long,
have burned my boats
in my efforts to grow.

Trapped in my walls,
but then I don't care.
Though you'd have fought,
but I lied to you so.

These days nothing calls
or tears at my hair,
though you'd have not
been lying so low.

Well, but you're gone
and now i so miss
those days when you sought
star gold n' moonglow.

Eight years I've known
that something's amiss...
how I wish i'd not
wished for you to go!

Oh eighteen and then some
that was so... so long.
Have I burned my boats
in my efforts to grow?
