A woman yawning like a hippo.

Tomorrow will be 3 weeks. I yawned like a hippo.. I didn't open my mouth for about a week after the surgery and I just held back my yawn.. I heard that someone said he was eating lettuce wraps too.. Since then, I've been yawning like a hippo too... the director told me. ...You told me not to touch it as much as possible because it tied the cartilage with a thread... Is it related to yawning?? How are you guys yawning?^^
