I think it is an important decision and it's significance is individual. For me, I think it meant I felt a certain degree of trust and comfort.

Also, I was just sick and tired of looking at the same ole stuff while averting eye contact. lol So I moved from the couch to the chair and saw things in the room more from her perscpective. I've only sat in the chair two or three times in 2 years. I think I sit on the couch because it sits lower and so it feels like child and caretaker and that suits me fine. Someday maybe I'll grow up!
