Mothers - Blood-Letting lyrics

I think it's about time I was leaving You're stumbling over words I don't believe in But I'm finding New legs to walk with I've been finding New knives to kiss with When you sleep Your body turns ghost-white And I can't help but feeling Like a fly on milk I crawled back into myself alone I am writhing with certainty I am dancing with the slow d**h Trembling like a drop of mercury I touched your wrist beneath the blanket No use now In trying to change our old ways When someone else's name is stuck Between your shoulder blades Here are my hands Reminding you of someone else's hands God is stuck Singing himself to sleep I am not the only one
