<human>: A little background. My wife and I, married four years, have always trusted each other. We have two children, both under 4. Life has been extremely hectic with raising them, both of us working fulltime, finances, etc. Therefore, there hasn't been a whole lot of time for intimacy for the past year or so. Basically, life has become very serious with very little fun for the two of us. Only when we're with the boys. We do go on dates with each other, but the romantic connection isn't there like it used to be. 

Last week, she told me she had to work late after work. Late meaning she got home at 8:30 PM, when before working late meant no later than 5:30 maybe 6. She hasn't been complaining about work as much lately. Well, today while folding laundry, I found see through black lace Victoria Secret panties with small pinkbows on them in the laundry. She didn't wear them with me. Last time I saw her wearing them was when she was with me maybe a year ago or so. The only panties I've ever seen in the laundry are her everyday panties. The only reason I'm concerned is because I found them in the laundry today and she had that late meeting on Wednesday of last week. Is this something I should be concerned about?  Are there circumstances when women wear sexy lingerie for comfort?

Can you condense the text into a few key points?
