First day in karate class

This was a day come true. After long searches and delays, I finally found a karate school and that too a nice one. It's five minutes walk from my house and the style practiced here is Isshinryu. I was thought some warm up exercises and the bowing method (also called as rei). One should bow before the teacher every time before talking to him and at the end of the class. Also at the end of the class everyone should bow to the hall (dojo) as a mark of respect. Rei is performed by keeping the feet in V shape with the heels touching each other, the hands on the side with the palms resting on the side of the thighs and with a slight forward bend with the eyes facing the feet and pronouncing something which sounded like "HOIZ".
