I know what you mean.
My MIL absolutely ABHORED anything new,
any change. Her car needed to be replaced, and she had a screaming fit about it after driving it home. This was reported by my BIL; I didn't witness it firsthand.
Thank goodness, as I would have been laughing, probably. That would not have gone over well.
[MIL disowned hubby and me many years ago, years before she passed. Thereby hangs a tail. <-- not a typo.]
I do dislike buying new shoes. My feet are weird, they like what they like, and they don't like what they don't. I buy a lot of stuff at Goodwill and Thrift stores.... but not shoes. My feet have to break them in, each toe has to make its own little depression to fit into.
Hubby did try something new that he liked, at least a bit: beets. I give him high marks for that. It's something I can grow in the garden!
