My sister has received an anonymous letter. It says it contains some 'home truths' about her and makes some not very nice statements about her i.e. she's a gossip, people laugh at her etc. It's not pleasant but makes no threats against her or anything. She is going to contact the police about it, I think she should just forget about it as its obv just some twat. I also don't believe its a police matter but she insists they'll be able to 'track down the writer'. I reckon that a) they won't and b) they've kind of got other things to do. AIBU?
