i used to be as single as a swan

i sit on my own at lunch
in class I'm on my own
i rarely talk to anyone
i am as single as a swan
then you come along
why did it take near death for me to recognize you ?
now i don't sit on my own at lunch
because i have you
now I'm not on my own in class
because i have you
now i am not as single as a swan
because of you
