This reminds me of when I was a kid and my very Scottish grandma did child minding for extra money. At one point she looked after these three siblings that were adopted from Guatemala. The kids had two moms. It was the 90s and I'm Canadian.
Now, you would think that even in the 90s most adults would see two women who live in the same house and have adopted children together and think "Harold, they're lesbians". My mom certainly did, internally, but my grandma never brought it up, leaving my mom to wonder whether my grandma was being uncharacteristically discreet or if there was something about the situation my mom was misreading.
One day my grandma needed a hand with something to do with the kids, so my mom came over to the house, whereupon she noticed that the two women who lived together slept in one bedroom, and said "ohhh, they're lesbians."
To which my grandmother indignantly rebutted, "they're not lesbians, they're Scottish."
According to my grandmother, you see, it's cold in Scotland, so women live and sleep together all the time and women who do this are not lesbians, because it's cold (????). Therefore, upon noticing two women living together in Western Canada, adopting children together, and sleeping in the same bed together year-round, my grandma had mentally categorized these women as Scottish.
