You live with Sara! How did you not know she had it?
I can picture the conversation over breakfast in your house:
Caoimhe - Damn, I lost my pink shimmery shawl thing.
Sara - Aw, that really sucks. Someone else must have lost one as well, cos Kerry handed one to me that was left on the back of a chair.
Caoimhe - Lucky for that person. Well, I guess I'd better go stick a post on the message board.......sigh!
