Very interesting to say the least. I really like how happy and busy you sounded. The call could not have come at a better time with you having plans. I am glad you told him about Mexico. He sees you just moving on with your life and leaving him in the dust. I would say yes to the Christmas card.
Oh something I read on 4060 that October to December are the worst for an mlcer. Covert and overt depression are on an increase. Some of course make more contact because of Christmas.
I am jealous of you going to Mexico. If you like to bake then buy some vanilla. You can't get vanilla anywhere else that is so good. Of course don't forget the kahula.
