Cell Phone Yoga?

Recently, a friend of mine told me of an experience she had in a yoga class. During class the yoga teacher had everyone in child's pose, he/she then proceeded to do some texting on a cell phone. The teacher never explained any reason to the class like someone close had a serious illness or something of a dire emergency, no it was general texting. Really...?? Do we have such an addiction to these phones that we can't even turn them off for an hour or two?!

Occasionally I hear a cell phone ring in my class. They are usually accidents (they forgot to silence them) but a couple times the students answered them. Again there was no dire emergency. I'm not sure if we need a new set of etiquette rules for cell phones or a reminder of why we do yoga in the first place, or both. This person probably never even thought there was anything wrong with multitasking while teaching yoga.
If we are truly in the present then distractions lose their pull on our attention. Yoga is supposed to help us wake up, stay focused, live mindfully and be present. We owe it to ourselves and others we come in contact with...
