There's A guy ....

Theres a guy who is always there,
standing right beside me,
he knows that i am blind,
but he can make me see

theres a guy who lives with me, he's always by my side.
he is very like me, in that his interests are quite wide.

theres a guy who is interesting, and always wants to talk, but sometimes i ignore him, i don't want to walk and talk.
