Does this sound like a neurodiverse thing

Ever since I can remember, I’ve always been able to make friends with people presenting as all genders. But there seems to be this unspoken rule that it is impossible for (presenting) men and women to be friends

Like, a man and a woman hanging out and just shooting the shit then going their separate ways seems unheard of at my age. Idk maybe it’s more of straight people thing more than anything, but it sucks 👍
