Is it normal that i find this annoying?

I'm a quiet person who's been described as serious.

Every time I see them, this person always talks about me like I'm not there, saying, "She's so sweet" multiple times, along with other comments. They'll also give an un-asked-for mini description of my character and maybe some comments on my appearance.

I keep a relatively blank face, even smile sometimes, but this grates on me. I think, "What the fuck do you know about me? Stop talking about me and for me."

I cringe inside when I hear them say I'm sweet, because it isn't really true. And to anyone who knows more about my character, it just calls attention to the fact that I'm not a very sweet person. A small part of me suspects that it's said in mockery rather than ignorance, but either way, it's gotten old.

It'd be too much of a pain to bother saying anything, though, and I'd just look like an uptight ass who was taking everything too seriously.

I didn't mind at first, but going through the same song and dance has become irksome, especially as over time I've come to find this person's loud, blunt behavior less endearing and more obnoxious. Though, they're still pretty funny and cool sometimes.
