No one could know how he was feeling, or what was going on in his mind but he certainly looked lost in his thoughts. The distant look of his said it all. And despite the demeanor he was portraying to the outside world, that didn't stop him from taking regular sips from the cup of coffee.
He had been thinking. Thinking hard. And it was most likely regarding important matters that didn't need the interference of others. Fortunately for him, no one had approached his seat since he began and that was more than enough for him.
Despite the noise emitting from the crowded cafeteria, he wasn't affected as he had half his mind cleared from external factors. The burger looked almost like it was untouched as he hadn't taken more than a bite from it but he made sure to constantly took sips from the coffee he had ordered alongside.
