Voices In The Wall lyrics

Chatterboxing numbers
talking silent,
softer somehow smarter,
Voices in the wall they are far
they are talking something
something that is small very tiny
speaking silently they are working hard,
making bumping they are doing something,
something that is small in the wall
they are fidgeting.
Small hands working scraping
something over here press your ear...
They want us out they'd
be gone by now if they knew how...
