i know! I can't figure out how much of it is an act for the camera or what!!
My guess is that he started doing it and he liked the "oh, Kyle, you're so silly and cute!" comments.
But even now, the negative comments about it are still better than no comments at all- so he just keeps doing it and putting it in the vlogs. Getting "engagement" from that is better than no engagement on his videos. But I'm sure it'll backfire on him soon enough- people can only take so much of stuff like that. (including Casey, I hope! For her own sake!!)
