Summer is when butterflies come out and play; they are drawn to warmth, brightness, and color. Summer is what it is, and despite the occasional thunderstorm has the most comfortable and consistent weather of any of the seasons. You don't have to wear layers of uncomfortable clothing in the summer, you can bare all and just be yourself.
It is easiest to see in the summer when the sun shines brightest and the days are long.
Summer is my favorite of all of the seasons; if it was up to me, it would always be summer, from now on until the end.
