I blow bubbles when you are not here

The story:

I was in the car with some friends and we
were singing this song as it was on the
radio. I sang my lyrics, and one friend said,
"what did you say?!?" i said my lyrics, and
she started laughing and making fun of me. I
was really mad at her because she's not the
brightest crayon in the box and often stays
stupid things herself. so how dare she make
fun of me?!?
