Early hours of this morning 79 yr dad was burgled scariest part is that they were in his bedroom while he was asleep, can't stop thinking what if he woke what would they have done. Worried they will come back now they know it's an old person living on their own. Need to increase his security but struggles with his hands so doesn't think he can manage a chain or bolt. Suggested yale lock but he worries he can't get out in emergency or I can't get in. Just want to kill the *.
