Hi BF - I hear you, I have NO sister's or brother's which makes it sad for me.
Nor was I able to have children, which is another sore spot for me.
Being Father's Day, well my Dad died in 1982 and my Step-Dad in 2004.
So, I can sort of feel what you are feeling. I am feeling down today, I guess because it's father's day.
Chin up! Thinking of you.......Hugs, Nikko
