DSister recently got married. Had meet the groom a few times, but not had to chance to get to know him. Recently, they were visiting, and we got to chatting about of lot of things. He seems really nice, I think they are a good match (her 2nd marriage, late 30s, no kids).
However, it was clear from the conversation that there are fairly significant things about her an her life that were not know to the new DH (career change, where she lived, etc. and others).
I got me thinking about how well we really know our partners!
