Thanks to both. Travelinglady, I don't think that I could ask her

Maybe she would think that I feel in this way because she did something wrong, and she didn't. I too like just staying with friends. Maybe it's even better when we don't do anything particular. But it's automatic...when we are just sitting silently, I feel that I should entertain her, if we are at my home. I'll try to think that maybe also for her it doesn't matter what we do...but it's not easy.
