The "I used to be...poems, and their variant, "I used to be...but now I'm" forms can be very fun ways to write about memory or cause and effect.
“Going To School”
by Caitlin L., age 7
I
used to be afraid of the toilet.
The blowdryer. I used to be
afraid of
taking a show. I
used to be afraid of being
home by myself. I used to
be
afraid of Shadow when he
tried to bite me when I was
getting on
the monkey bars. I
used to be afraid of the bus
driver in first grade.
I used to
be afraid of boys with long
hair that would ride the bus.
Now
I'm afraid of the bad
dream layd who lives under
the bed.

I
used to be a kid but now I'm
a boy.
I used
to be m but now I'm n.
I used to be an umbrella but
now
I'm broken.
