Am I the only one???

Okay so, I've always had some type of blanket or pillowcase that I carry with me around the house. I carry it around because when I'm just sitting on the couch or about to go to sleep (it's a firmer cotton type fabric that you can fold the edges to make it kind of sharp) I fold it and start to rub my fingers against the edge. I think it started when I was little because of the living situation I was in, but now it's a habit and I was wondering if anyone else does this😂 My little cousin knows that I do this so when I want to spend time with her over her house, she always reminds me to take my pillowcase.
