If her MS and heavy meds are causing this impulsive behaviour it's actually really sad and I feel for her, someone allegedly returned the items so possibe others know about it.I knew someone with Parkinson’s that went down hill over many years. Unfortunately they refused to retire in a highly regarded profession and ended up creating a huge mess for everyone around them.
Sad case where they couldn’t accept what was happening to them.
Health is so important. Good on @Inruin example where they owned it. But for many it can be a major life change where decisions are clouded by powerful drugs.
Does make you wonder how she can hold down her MP responsibilities with those symptoms, if it's true. Is kleptomania a diagnosable medical condition in the DSM Sup?
