losing it again

i thought i could describe what's dry
but i ain't seen nothing yet
i fell into a pit of sand
and came out soaking wet

i thought i could tell round from straight
perhaps i'm not so smart
i took the straight and narrow road
until i reached my start

i thought i knew my ground and sky
but i don't understand
i rode a train up in the clouds
and flew a plane on land

i thought i knew my own true self
but i really don't know jack
i took a look in a looking glass
and saw my buddy mack
