person A: I just have to brag on my son.  He hasn't always been a strong swimmer_comma_ but tonight_comma_ after a summer of practice_comma_ I was able to see his amazing improvement!
person B: That is amazing hard work pays off and I think it is great that our kids know how to swim.
person A: I agree.  He was never timid about swimming_comma_ but he just wasn't real good.  But tonight_comma_ he was diving (more of a belly flop) and swimming on the deep end.  
person B: How old is he that is great my daughter is 5 I think that will be one of my goals for the remainder of the summer teaching her the basics of swimming without her life jacket. 
person A: He is 10.  He has been around water for most of his life; but like I said_comma_ he hasn't always been strong.  This summer_comma_ he saw the need to improve.  I think that he took his own initiative is what has thrilled me the most.
