I am so sorry to read this. I have been visiting with my brother the past two days and have just felt compelled to make sure my grandkids see him, know him and spend some time in his world. We do need to go out of our way to make these imprints in our memories, both for us and for them. We can never know what the future holds or how long we will be of this earth. It sounds like you have had many good memories with your sister and I hope those will carry you through the shock of her passing. My thoughts are with you.
