Not Quite Getting It

Michele and I spent Christmas day, Monday, and Tuesday visiting with her mom. On Tuesday morning I had a long, private talk with her mom. She knows that I'm transsexual and Michele explained to her what SRS is before we went out to AZ in August. So, I was quite surprised when she asked me when I adopted my kids. I explained that they are mine, that I am transsexual, that I am their father. She couldn't seem to wrap her head around this idea and asked if the kids know I'm transsexual. She asked what the kids call me. She went on to ask who is the woman that they stay with when they're not with me. I explained that she is their mother (I wish I had remembered to use the term "birth mother"). Again, she wasn't quite grasping the situation. I don't think we discussed this any further but I think we'll need to come back to it at a later date.
