I went swimming at five p.m,. because I thought there would be lessfewer people at that timethen.

You use "fewer" for things you can count, like people, and "less" for things you can't count, like water.

What thewas worst was that they were playing in the pool rather than swimming, so I had to swim very carefully to avoid crashing withinto them.

There was a young couple always standing in middle of the pool but never swimming.

The boy played under the water sometimes, or tried to catch the girl, who was walking girlaround.

I had to changed my wayroute from time to time.

Thanks to swimminghaving swum a lot, I could swim easily in the complicated situation and enijoy myself.

I saw a little boy who was a little overweight and looked like a Sumo wrestlers, squatting deep under deepthe water, then jumpeding up, over and over again.

I thought she swam better than most of the people who were swimming in the pool.

I made athe mistake that I shouldn't eat of eating (food containeding sugar, i/sugary food). It made me feel a little disgusted and thirsty when I was swimming.

However, I have swam for 70 minutes.
