"Yeah? Well I'm glad I didn't waste my time trying." He scoffs, he's visibly annoyed and all he can do is draw another long sip out of his coffee. "So tell me, does everyone know that little fun-fact or do they drop it on you after you've embarrassed yourself?" He probably doesn't mean to be so rude, probably, but he's an asshole. "I'm gonna blame Jason." He says finally, darkly and mostly into his cup.
