David, so sorry to hear the news of your Mom. Sam and I would like to extend our sincerest condolences to you and Karen, Derek and all of your families. I hope you find some comfort in knowing that you were a loving and devoted son and that it must have been a great joy to her to have you caring and spending time visiting with her so often. When you spoke about your Mom, I was struck by what a special relationship you seemed to have and always with a positive sense of humour. Wish we could be there tomorrow with you. Thinking of you.
Love and Hugs
Marisa and Sam
