My wife behaves very similarly. Often she apologizes for things that I don’t even register. It’s a difference in how we grew up. I’ve mostly settled on ignoring it now but early on I encouraged her to think about who she’s apologizing for, and if she’s doing it for me I encouraged her to stop. Not only do I not need it, most of the time I don’t even notice whatever minor transgression occurred she thinks needs to be apologized for.
Now if she does it the apologies mostly go unnoticed too because it’s not for or about me, and if it’s what she’s comfortable doing then that’s ok.
I actually like vinegar by itself but it’s too potent to just drink it straight. Instead I’ll get a bunch of green onions and let them soak in the vinegar, then I suck the vinegar out of the green onions and enjoy the onion itself as a crunchy snack after.
