Just got a letter through the door of my student house addressed to someone who doesn't live here anymore.

Wouldn't bother me except that it's hand written. Wonder if the sender will ever know she didn't get it...? Or why she thinks she still lives here?
Is it wrong to read it?
Hand-written letters are few and far between these days, seems a shame for someone to miss out. Must write more of them to my friends and family.

Although should check addresses first. Wouldn't want some snooping new occupant to get their hands on it
