Doffy's tired of feelin' like he's talkin' to a darn wall n' not his actually very much so livin' n' breathin' lil' sibling. N' at the very least- Doffy gave ya the benefit of the doubt n' jus' assumed ya be jus' a tiny be shellshocked or somethin' but nah. Yer were jus'... Straight-up ignorin' em'.
N' for what purposes? Really, Doffy wanted to know what the heck ya were tryin' ta solve or what stupid lil' point yer were tryin' to make by ignorin' em' like this. 'Cause at this point it was just childish. Humph! And people hafta the audacity to try n' call em' the crazy one 'ere like he was the one who had to use a whole freakin' notebook jus' ta tell the poor lil' servants what ya wanted ta drink or somethin' else lil' like that. So... Ya think, obviously, 'cause ya were the one really causin' the problem's 'ere by not talkin' at all for some reason n' stuff ya would think Doffy would always been on yer rump 'bout how many avoidable inconveniences yer were causin' for em', right? Well- that's not exactly how things went 'cause neither the Donquixote Family nor Pirates, n' especially not Doffy 'emself in any circumstance was in any way, shape, or form "normal". Nah. 'Sides it was jus' more fun to freakin' watch those lil' cretins wrigglin' n' squirmin' in fear like the lil' useless bugs they were n' then jus' put the scared lil' things out of their misery after he was done playin' n' toyin' with em', course! 'Cause Doflamingo was just that petty n' sick in the head, not like that's up for debate or anything.
And it really ain't rocket science nor does it take any sorts of rocket science to figure out exactly what n' why Doffy acted the way he did- 'Cause who the heck was goin' to tell em' what to do? Absolutely freakin' nobody, 'course everyone else's cowardice would only cause more problems n' trials n' tribulations alike for Doffy since ya still haven't budged, not even a lil' bit n' surprisingly- the infamous "Heavenly Yaksha" 'emself was actually gettin' a tiny, wee bit worried 'bout ya.
