Happy Birthday times two

Today we had a birthday supper here at my house for my son and his mother-in-law who share September 13 as their birthday.  It was a fun relaxed evening; I cooked some old favorites, and everyone seemed to enjoy themselves.  I couldn't help remembering though that my husband and my stepmom shared a birth date, and for many years we celebrated their birthdays together - usually at my house.  All seemed well then too.  It wasn't until a few years after my stepmom died that my husband confessed to me that he had often resented having to share his birthday celebration. I never knew.  However, I don't think the same thing will happen here, mainly because my son and his mother-in-law really seem to like each other.  It makes a difference.
