For me, I came out a few months back (F47).
My mother replied, "I hope you're not expecting me to act surprised, it's about bloody time, cup of tea?" And a hug.
Then I had 3 sister's on video call together, I only told them I was thinking about dating again and 2 of them said "women?" before I had a chance to say anything.
They obviously knew me better than I did 😆
