Dad just called (from work) and said that they have taken Mom into surgery!!!
Apparently she went in about 1 pm. (It's 4:15 now, so they are hopefully well underway.)
This is such great news, because it means that Mom did not have to wait terribly long today. God continues to answer!
We don't know how long Mom will be in, but I will try to post something when she's out. I know you are all concerned (with us!) about how this pelvis surgery goes!
