Because it's been established that i don't want to tell him that, and he's trying to make me seem like a hypocrite.
I told him that i find it suspicious that whenever i ask for proof of something he says "it's private", (even when there doesn't seem to be any reason why it'd be private), which seems to be what he'd say if there was no proof and he wanted to keep the benefit of the doubt.
He seems to think that making statements that require proof and then refusing to provide proof is the same as denying someone random information.
