I am moved to condolence for your family. I am the eldest of my line, and have endured all my forebears' departure before me. I empathize deeply with the pain the prospect of their departure must entail, but I envy you that prospect even so. It is good to attend as you have to whom you will not forever be able to, however difficult it is, and wise to spare you regret at the loss of time together you may yet have. I am sorry your grandmother is in ill health.
Thanks!
