Is it normal i eat meals in reverse?

Who the hell got to say what's for breakfast anyway? It doesn't even make sense as most 'breakfast foods' are fucking glorified candy. Yeah, I wanna wake up and eat some goddamn candy first thing. Oh and I can't have eggs for dinner unless it's quiche or some shit. Ohhh...ohhh...and I can't have MASHED potatoes in the morning, only cubed or shredded, that's pure logic right there. And don't even get me started on restaurants that don't serve a full menu all day. Fuck you, breakfastman.

it seems like a personal preference, you can eat whatever the hell you want whenever you want, who is to stop you?

Technically, breakfast is the first meal of the day. It can be anything and any size. Breakfast means to break the fast from the following night. It doesn't mean eggs and pancakes. So it is basically impossible to have dinner before breakfast.
