First day of lessons

Yesterday was our first day of swimming lessons. I taught 10 lessons today ranging from parent-child swim a and b, pre-school level 1 and 2, and learn to swim level 1. I was so tired at the end of the day. The sun really drains you over here. I was really nervous to teach the parent-child class because I wasn't sure how adults would take instruction from a 21 year-old, but it went very well. All of the parents were very kind and there is some really cute infants and babies in the class. I think I sang "The Wheels on the Bus," 45 times yesterday. A few of the kids were very timid about getting in the water. I had about 4 criers through out the day. The pool is at least 3 feet deep in all areas so it is hard with the pre-school aged classes because they have to go on top of thing called "top docks," which are like a table in the pool. 4 of the kids jumped off of them while I was teaching yesterday and started sinking to the bottom. A little scary.
I have always been known to get a little color through out the summer, but this time I have turned into a different race almost and it has only been day 1 of being out in the sun. The last two days have been black flag days but since the kids are in water, the lessons still continue.
