I don't think I'm going to change lanes at the swimming pool.
Is there a reason for not changing lanes?
I've heard of accidents caused by doing such things.
That's good of you to follow the rules in public to prevent accidents from happening. The rules are there for a reason and this one will help keep people safe.
Yeah, I bet I would get someone hurt if I weren't careful.
Good on you for being cautious. Have fun at the pool.
