My advice to her is to buy the biggest safe she could afford,then spread the word she ‘s got guns and money in there and secrets about all her roomates in there also ..Then watch them try to open it and bank away on it for weeks in her absence ,giving them something to keep them busy while leaving her alone ..
Then after they call the police to force her to open it , telling lies to the police about what a threat she is..Then when she is forced to open it for all to see…It is empty ! She has the last Laugh with all them fools..I actually had this experience as a kid where others kept stealing things I PAID FOR. I
BOUGHT A TRUNK and put the biggest LOCK on it I could find…and waited as they banged with hammer and saw to open it….after weeks of hard work they finally got it open…..to find it empty….I was long gone …..It works….!
