i don't know how deep the ocean is

i don't know why the sky is blue

i don't know what causes thunder

but i do know

i love you

i don't know how an engine works

i don't know where butterflies fly to

i don't know why the grass is green

bit i do know

i love you

i don't know how to write a song

i don't know how to make a great barbecue

i don't know how to do a cartwheel

but i do know

i love you

i don't know what i ever did

i don't know what how to construe

i don't know what magic brought you to me

but i do know

deep in my heart and soul

i love you
