Missing cigarette

Yes!

It finally happened!

Today, she smoked after breakfast and before lunch.

We had an activity all afternoon, during which there was no opportunity for her to smoke (she did bring cigarettes though).

I had an activity in the evening, which means I wasn't around for her usual after-dinner cigarette break.

I just got back, and there is one stick missing from her pack. I'm certain, because she brought a new pack with her to the afternoon activity. That pack is now open, and one cigarette is missing. There is also a butt in the balcony ashtray which wasn't there this morning, so she hasn't tried to hide it.

She probably smoked it during kid's screentime, which is around 8 PM. So approximately 8-9 ours since her cigarette before lunch.

We'll be heading out for her nightly cigarette(s) shortly. Should I bring it up? Or not mention it?
