One day, I saw a duck quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack, quack quack and quack quack which made me realise that not everything you say should make sense to someone who doesn't get you. So just quack quack or vow vow or meow meow or whatever you like. Just thought you should know.
