How often do you and mum-in-law spend alone time? What activities do you carry out to create a bond?

I have not made it a habit to spend time alone with my mother-in-law. Of the few occasions I did, we spent the time preparing food for the rest of the family. I've made dumplings and CNY goodies together with her. There was once when we were alone and she was clearing some old stuff. She started showing me photos and telling me about how it was like bringing her children up etc.
