substitutions

i rolled myself just like a wheel
to make it up a hill
the taste of x and polka dots
disguise the bitter pill

i made my back a turtle shell
so i could cross the road
next time i'll get an umbrella
to wheel my extra load

i watched a wall of shadows
so i could see a sign
i tried to connect all the dots
but couldn't make a line

some people talk in ice cream melt
some whisper words in creek
i wait under the mailbox door
and lick the stamps to speak
