Happy to lend a hand
I’m pleased to print your letter. Everyone should be so lucky as to have a caring and generous neighbor like you. When a death happens, the most important thing is to maintain contact with a grieving family and observe the Golden Rule as you have been doing. The time to be a friend is when someone needs one.
Keeper of the secret
You are obviously a caring and sensitive woman. I agree that your children have a right to know they have other blood relatives. I’d be very surprised if the young women your children are related to were shocked by your contacting them. They are older and may have some recollection of their siblings. However, before discussing this with your teenagers, I recommend that you make the initial contact to be absolutely sure the two adult siblings would like to meet your children.
