My brother has just text to say niece has just come out as a lesbian. I said fab as no woman would choose to be straight. Then checked she wasn’t upset etc. and all happy. He joked she wanted a card to at ‘yay’ and I said I would oblige.
I am out with a friend so mentioned it and she (straight woman FYI) said I am not taking it seriously and need to act like an adult about it.
YABU - she so right, you are being silly and ride
YANBu - you’re friend is ridiculous
