I am so sorry to hear about the loss of your Mom. This is a most difficult time at any age. Hopefully, your many fond memories and all your family will ease the loss....
I am sorry to hear that your mother , mother in law and grandmother will no longer be a living part of your lives. I met Grace many years ago when we exercised in the pool with a group at was then the Holiday Inn . Since that time whenever we met with a group for lunch or just at various places around town she was always gracious, friendly and interesting to talk to. May all your memories of Grace help you at this time.
