open the door

Open the door and they will come
be careful just whom you invite
you can become to them alike;
and if you let so many in
is it still your house the house you're in?
is it still you or do I greet a friend of yours
when I see you? and if this happens
is this wrong, or it will simply make you strong?
open the door, I told you so
they are all teachers and you are teaching them
a lesson too. don't be afraid to leave your footprint
in the sand, and on their souls.
just remember not to hurt yourself
when you are sharing and enjoying
the sips of coffee and the bits of realty
that your friends have brought for the big party.
