I always wished I had been an only child. Have a lifelong Dem sister who cried for two days , she told me by letter, "now that Hillary lost to Trump that means I won't live to see a woman president". She hates Trump viciously. Last in person or on phone contact with her I had was 1987 (too recent for me.)
The great humor writer Jack Douglas wrote a book My Brother Was an Only Child.
Sympathies. I have a sister too and she triggers me but it’s just a personality clash and there was a big gap in our ages but at least in politics we are in agreement. Both of us are conservative.
