Adam: explore the building

You roam the halls of the building for a long time looking for a prey but the only thing you find is a cat pissing in a corner. This morning the place seemed a lot nicer, apparently it's an half abandoned building nearing the ruin. Eventually you find an old lady trying to open her door.

Her blood is thin and the nourishment you get from it is close to nothing.

You decide to leave the building to find some more interesting prey on the streets when you hear a juvenile laugh coming from a corridor behind you.

Do you follow the appetising giggle or do you go back to the streets?
