Exactly! I have had several friends, that when they finally "came out", every one they told asked them what took them so long as we'd all known for years before them that they were gay.
Yep! Husband’s cousin was married with a daughter, but I said “She’s a lesbian.” I was laughed at because... well, she was married with a daughter! Couple of years later she left her husband for a woman. My gaydar is hardly ever wrong and I’m still convinced it’s a matter of not being wrong. Just a matter of time.
