There are things that make me upset. Things you know and things you don't. one would be being given something clever and confusing. I'm sure you could remember my four -digit number and track me down. Now if you have and I haven't found you, that means you win. And well. I'm not sure what that should mean. You're welcome to suggest rewards. But there you are. And have found me.
