Your co-worker

As your working vigorously, you see a new face enter the company's doors, someone unfamiliar, he looks young for this company, but you chalk it up to his baby face.

you come to him as soon as your break starts, you see him surrounded by other co-workers,but for some reason he notices you, amongst the small crowd around him

"Oh hi there!"

he says with a lively and brisk tone, almost like he's happy to meet you
