The context of the following conversation is Lee wanted to do a swimming work out so he threw a toy in the deep end of the pool and wanted to see how fast he could get it.:
Lee says I've been trying to work out more, and I heard swimming is good for your body..
The friend responds It really is, because you are moving everything..
Lee responds I throw a toy to the deep end and then I just jump in, swim to the bottom and collect it..
The friend responds Do you think you will take classes?.
Lee responds Eventually, I don't know when yet..
