hmmmm. I am extremely humble about my talents and knowledge IRL. If someone starts talking about numbers, I may say I have a "little knowledge" about them. Truth is I am a number wiz. If I know someone is an accountant or mathematician, I may not even mention the "little knowledge", I may just play dumb. It doesn't mean I am lying, it just means I don't want them focusing on that part of me. I get a little embarrassed by it to tell you the truth.

Another example: My H is an amazing pianist. Most of his coworkers and even his recording clients have no idea he even plays. His friends know, but unless they are close friends they have no idea how good he actually is.

Some people don't like to flex their knowledge. Perhaps it isn't that your t doesn't like you or is trying to buffalo you?

Hope this helps.
