Hello, Densest of the Dense Thickhead Kiwi!
Yes, when a girl in a shop comes up to you immediately and says, "I'm not going to lie, that is the coolest hoodie ever" about your BLARINGLY GAY RAINBOW JUMPER it could be a little hint. And then maybe, just maybe, you could catch on when she says, "And that belly button ring, I've got it too. The one in your ear." You could respond something with something more than a chuckle and a, "Oh, yes, I like wearing belly button rings in my ears instead." Which she complimented. And what is the piercing? Oh, it may just be the two-female sign on a rainbow background!
And if THAT isn't enough? Perhaps the fact that she smiles, laughs and looks you in the eyes as she silently directs you toward your friends when you have obviously lost them. Then further conversation and an authentic goodbye when you leave.
Kiwi, sometimes you are a putz. I love you, but you are totally a numpty.
