You don't miss someone at 2 in the morning, you're all alone.
You could miss anyone when you're by yourself.
You miss someone when it's 2pm, and you're surrounded by other people, but you just want that one person.
You miss someone when you're busy at your job, but you still find yourself reminiscing.
You miss someone when you're working-out, going for a run, and they're still in your head with every step.
It's easy to miss people when you have the time, when you're lonely.
But, the people who truly mean the most, the ones you really miss, are the ones you think about when you don't have the time to.
2pm people.  
The ones that occupy your thoughts no matter what.
