On my way to Shacharit this morning before I got in my car I saw my neighbor’s purse on the sidewalk. I guess it fell out last night when they came home late and they didn’t realize it. I have to rush off to Shacharit and go to work and I know that they are not awake and she really needs it today. Can I hang it on their front door and they will find it when they go to Shacharit or to work or School this morning? Or do I have to keep it in my house until I come later?
