I emailed a local school to ask about visiting because we are thinking of sending our son there. My email didn’t state my title and referred to “we” and “our son” but didn’t say explicitly that his other parent was male, or that we were married.
The email came back “Dear Mrs McJessie” and asked me to give my husband’s full name if he was joining me on the visit.
AIBU to be very surprised that they just assumed that I (a) went by “Mrs” (b) was married and (c) was heterosexual? In actual fact they were correct on all three counts, but that’s not the point- I thought that people were a bit more careful to assume nothing in this day and age.
