"Earth to Charlie!" Don took the chalk from Charlie, grabbed his shoulders and shook him a bit.
"Lemme go!" he pulled away.
"Mom is having one of her bad days, yet she worries about you."
"I've gotta get this done" Charlie mumbled as if he hadn't heard.
"You don't deserve for her to be your mother!" Don growled.

"It's kind of urgent" Charlie continued.
"I can come back later" the student kindly offered, and left.
Soon it was just the two of them.
"How long have you known that David Lev was my father?"Charlie got to the point. Instead of answering, Zeal looked at the younger professor with his mouth open. "Greg? How long have you known this?"
"Since you were a graduate student here" Zeal said after a pause. His father, your grandfather, was my doctorate advisor. David told me about the...situation when you enrolled here."
"What exactly did he say about it?"
"That he had an affair with a married woman only to find out a few years later that she had a son that looked like him." While surprised, Zeal was happy that Charlie and David could finally met, though he realized that it must have been painful for his younger colleague to find out the truth.
"What else did he say?"
"That he hasn't been able to reveal himself, but wanted to know how you were doing, and help out in any way he could"
"So he was the mystery donor all these years"
"Yes. I helped him make the arrangments."
"Oh..." Charlie's tone grew a bit sharp as a part of him felt annoyed that he had been lied to by yet another person.
"He made me promise not to mention anything to you"
"Does his family know about me?"
"He told his wife when he first found out, and he told his kids when they were older."
"So, basically my mother was the obstacle to us meeting" Charlie commented in an annoyed tone.
"So...do you want to meet him?"
"Yes, I do"
