If David really hadn't noticed, he would have said "I have no idea what you are talking about."  Dontcha think?   If this would have happened with me and Freddy, I would have sent another text that said "Really or are you just saying that to be nice?" and he would have said "Really" and I would texted one more time "now I don't know if you really mean it or if you are just being nice" at which point he would respond "I'm really the head of the Quickie Mart. Thank you, come again"...which is a really obscure Simpsons reference which no one will get, but in Freddy's world it's my que that he is done with the line of questioning and I will never know the real answer.
