Context: Mom has told me a dozen times already how much fun she had , and how much she enjoyed talking about this or that with somebody in James ' family . They were all very welcoming of her , too , and I really hope that the memory of this does n't fade , so she 'll be more likely to join us in a smaller family gathering with them soon -- like a Thanksgiving or Christmas . I really do n't feel like I had the time to worry about how mom was doing during it all , so it was a huge relief to hear from her and others just how well everything went . Honestly , I spent most of this entire week just smiling .
