Why does the yawn continue???

I frequently travel in trains and have noticed that if someone yawns atleats two ppl yawn after him, and now since i noticed it i cant help yawning sometimes 2!!!

I once yawned after seeing my cat yawn! What’s up with this?

Already covered by the master…

No disrespect to Cecil intended, but…

Dr. Suess covered this one years ago. Didn’t you folks ever read “The yawn that went around the world”?
It started with the littlest Who in WhoVille, and from there got out to Horton, who spread it around the rest of the world. :wink:
