Do you think this sounds like bullying?

I went to breakfast with my uncle and niece. My Neice was mad at my uncle for some reason. He was like "look, she's grumpy, then he touched her sweatshirt a couple times. She was like "stop!" Then she moved down the table for the rest of the time. Was that bullying? I feel bad because I just thought they were joking around so I chuckled but it seemed she was actually upset about something.
