You'll turn around one day and realize that, while it's technically Summer, Summer is technically meaningless. You're still going to the office or factory or lab or spaceship, Monday through Friday. Summer will eventually bleed into Fall which, while it's the start of a brand new semester for some, is also meaningless to you. Apart from the weather, there's no difference between the Summer and the Winter, it all blends together, work, family, weekends, in the continuous ribbon that is your life. And most people don't even realize they've had their last actual summer until waaaay after.
