Having the same sence of humor proved crucial for me, next to loving pets. I dated someone once and when she asked why I asked her I told her I liked older women. She was 3 days older. (And not amused)
I felt totally comfortable with a girl I met at a forum meeting we started seeing each other more. She had pets and the same sence of humor. She’s my wife for 14y now, we have loads of pets. On my birthday I get gifted a younger wife, on her birthday she’s rescued from an old man. She’s 6 months younger.
