Summer eating is so different

what is it about the Summer where you truly eat differently than at any other time of the year? is it because the heat? is it because of the extra Sunlight? what makes me feel this way? in the Summer it's either on the Grill or some cold cuts,but avoiding the bulk of stuff that I eat in the fall,Winter&Spirng. One Season of the year changes all of the foods i might crave. i don't want no Hot food per se,but the usual quickie Sub&some fries. June, July,August&Early September have a flavor all there own taste wise.
