person A: When I was a kid I almost drowned so I would be nervous getting in the pool...but since my parents put me in swimming lessons I gained confidence and even joined the swim team
person B: Wow_comma_ good for you finding the courage to overcome your fear! I can understand why you were nervous after what you went through.
person A: Yes it was scary.  But I'm grateful for my parents for nipping it in the bud...sometimes that kind of fear stays with a person for the rest of their life
person B: I completely understand. Your parents sound like great people.
