Dive, that is the last resort, the person might have police History & this would give her more reasons to go & knock on ES door, ES, I would ask her in when she brings your post, offer a Brew then explain that you have a very Strenuous & demanding job & needs your full attention, all this person want's is company & someone to talk to even for 10 mins, that may work wonders, If not, just ask her does she have a Social Worker & see if you can get her Tel No, But in a Nice sort of way.
