Red indicator light on dash for passive alarm

Ok last night I get out of my car to come into the condo. I notice a red light flashing in the dash. It's the indicator for the car's passive theft alarm system.

So I look at the owner's manual and it says it flashes when the system is armed. So this is supposed to be normal.

But here is the catch....I swear to God that I never saw that light flashing on the dash before. And I have now had the car for almost a year and a half. I really think I would have noticed it before so I have to believe it just started flashing. But maybe I just didn't notice it before....but when you park and it's dark out it's almost impossible not to notice.
