Toddler daughter gives mean/dirty looks to EVERYONE

My daughter just turned 2 this month and recently has been giving anyone she interacts with (except for me and her father) the dirtiest looks! She doesn’t do this as a game or anything, literally anyone who tries to engage with her gets this nasty look and then I usually end up having to give a reason she may be doing this to them like “oh she didn’t get her nap today” or something. I’m really beginning to worry that she just does not like people! She’s playful and fun with us so it makes me sad that no one gets to see that side of her. Even her cousin who she talks about constantly got these looks today. 😢 Has anyone else had a baby who acted like this? Is it something they grow out of?
