A badly needed reminder

"GOD-DAMMIT!"

A string of curses flew out of his mouth as he tried to hop his way over to his easy chair. His tie askew, he held his foot in one hand while he ran his other through his wild tangle of hair. He stared at his undecorated room, complete with a beat up mattress and a threadbare sofa, and wondered, not for the first time, what the hell he was doing. He barely managed to make rent this month, he was still eating an all ramen noodle diet, and still needed his parents to pay for his phone bill. Basically, he was still living like a college student. He had had this job for a while now and he was getting nowhere with it. With a sigh, he resigned to the only option he had left. He would take up his parents' offer. He was logging into his email to respond to their message when he saw it. A new message. Opening it, he saw a name he hadn't heard in years.

"Dear Mr. Williams,

Hi! It's been a while! I just wanted to thank you so much. I just got my acceptance letter for Princeton and I honestly couldn't have done it without you. You were definitely the best English teacher I've ever had. I was hoping you would be able to attend my graduation ceremony on the 21st? Thanks again for everything!

Sincerely, 

Robyn Smith"

A smile spread over his face as he declined his parents' offer. He finally remembered why he had decided to become a teacher.
