Begging for 100% solid proof that he was reimbursed won't magically make proof appear. We've got someone saying he did reimburse – someone who has nothing to gain from making that up (which, btw, should not be confused with considering Pirate "trustworthy"), and someone who's either avoiding the question or has poor writing skills.

So, it's not "us" making you frustrated, it's the situation and what we have, so far. And that situation demands asking questions.
