Life happens, people get busy, you forget to reach out to some family and friends,
and get their part before you know it, and now it feels awkward to reach out to them for no specific reason.
But that's actually exactly why you should reach out. They will like you as busy as you, and they will appreciate your thoughtfulness and continuity.
True connections are rarer than you think.
Don't let them fade away just because you were too lazy to write a message.
What will happen is that you will increasingly have a society with more and more people craving for genuine interaction, and meaningful friendships, but where everyone also ended up isolated and lonely.
Just because they ran in an ocean of distraction, the summer started to forget how to nurture deep bonds with others and the joy that comes with it.
