BHP Billiton spent a lot of money to build a new skyscraper in the Post Oak area. Holly already worked on the 22nd floor of one of the older buildings, but BhpBilliton decided they needed a new one. It was finally ready in the spring and Holly packed up her stuff and moved to the new office on the 13th floor of the new building. One fine afternoon in May – Ivy’s first day out of school, in fact, we decided to drop by and check out the new place.
