While speaking with someone the other day, I was reminded of an experience I had while growing up.
My mom and dad moved into this house in South Dakota and started doing all sorts of changes. They re-carpeted the living room and some bedrooms, and re-wallpapered a few rooms including the family room.
We all had to help, and it took FOREVER to scrape away the old wallpaper and get the wall ready to put the new stuff up. It was a simple wine red and pine green design, but they put in this ugly duck border.
My mom wasn't too keen on it and after years of me asking why they didn't change it after putting it up, she replied, "I don't know. We just put in so much work. It seemed like too much work to make any more changes."
I think that also applies to relationships. Sometimes we find ourselves unsatisfied with the situations we've put ourselves in, but we feel that we've put in too much effort to end things. Instead of seeking happiness or working out differences, we just "leave the wallpaper alone" and keep things as they are.
Sometimes, a change of wallpaper gives a whole new life to the room.
