Shift happens

My yoga instructor said "shift happens" this morning as I dangled on the edge of my left foot. She seemed so genuine in her statement that I tried really hard not to let my laughter escape my throat. But to no avail. If I was going to hold my posture I had to let it out. Then she turned to me and said-I kid you not-"see it's happening already." All I could think of was my son's new word for me. Apparently I'm a "yogaist." So then I had to really let it out...all that "shifting" led to an earth shattering realization. I can never, ever just giggle. I'm a laugherist.
