Who can it be knocking at my door Go away, don't come round here no more Can't you see that it's late at night I'm very tired and I'm not feeling right All I wish is to be alone Stay away, don't you invade my home Best off if you hang outside Don't come in, I'll only run and hide Who can it be now Who can it be now Who can it be knocking at my door Make no sound, tiptoe across the floor If he hears, he'll knock all day I'll be trapped and here I'll have to stay I've done no harm, I keep to myself There's nothing wrong with my state of mental health I like it here with my childhood friend Here they come, those feelings again Who can it be now Who can it be now Is it the men come to take me away Why do they follow me It's not the future that I can see It's just my fantasy Who can it be now Who can it be now Who can it be now Who can it be now Who can it be now
