What Are The Symptoms Of Kleptomania?

I have a long time friend who was on a day trip with 50 women and she shoplifted from a famous hotel we isited, she was caught on camera stealing a blouse and security came on the bus and told her she could be arrested and took her drivers license and retruned it to her. She didn t act anything but normal an never acted alarmed. She proceded to act normal with us as if nothing had occurred. She even cam with her husband of many years to a dinner with friends who knew the situation and she acted like nothing had hAD OCCURED. IT HER BEHAVIOR AFTER THE INCIDENT NOMAL FOR A KLEPTOMANIAC?
