When I say I don’t want to get married or have kids I am sometimes told: “Oh you’ll change your mind!”
Psssst, here’s the secret: I already have.
I used to (vaguely) want children at some indefinite point in the future and I used to think I might marry someday, probably for practicality. Now I am opposed to both.
I have already used my “when you’re older you’ll think differently” card. Don’t you know you only get ne of those?
