<human>: A good friend of mine is going through a very stressful time at work. She's been working late daily and sometimes during the weekends too. I've been through long working hours too at work myself, a few years back, so I know that it can be frustrating and very tiring. Is there anything that I can do to ease her pain or help her feel better? 

When talking to her maybe I should try to hide anything that might show that I'm not working as many hours as she is, so that it doesn't make her feel more miserable? Should I bring up her work topic or avoid it from my side? I did mention casually that it seems like she's having a stressful day with a lot of work. But she didn't add anything to it or didn't vent out anything. So I thought that maybe she doesn't want to talk about it. Maybe I could just tell her that she could vent out stuff to me if she wants.

But with that comes another problem. If someone's venting out about work or something, how can I make that person feel better and more relaxed? If I just agree they might feel more down? If I don't agree they might feel like I'm not understanding their problem?

Can you condense the text into three sentences or less?
