Weirdly if it's pets or inanimate things I seem to default to he/him, but with people I most often do they/them! Finnish doesn't have gendered pronouns so I often might accidentally go with they/them even when I know the person's actual preferred pronouns fjjfjd 😭

He/him is such an everything pronouns for me, I use it for essentially anything that isn't explicitly something else. I will often mess up and use he/him. Especially with neutral pronouns.
