How to fix this implicitly convert error in c# with if-else statement?

Can you help me with this? I'm getting this error in my code:

Cannot implicitly convert type 'bool' to 'string'

I've searched on the internet to fix this and saw stackoverflow questions still not fixed. The code is

using System;

namespace MyApplication
{
  class Program
  {
    static void Main(string[] args)
    {
      Console.WriteLine("How are you?");
      
      string choice = bool.Parse(Console.ReadLine()); //Error in this line
      
      if (choice == "Fine" || choice == "Good" || choice == "doing well")
      {
        Console.WriteLine("It's great to know that you're" + choice);
      }
      
      else if (choice == "bad" || choice == "not good" || choice == "not so well")
      {
        Console.WriteLine("What happened? Why" + choice + "?");
      }
            
    }
  }
}

A question in stackoverflow recommended me to use bool.Parse or bool.TryParse before ReadLine. Used so but still errors.
