Mr. Smith had joined a high school as a Chemistry teacher due to his transfer from another city. You, an Economics teacher (30 years old), had talked with him a fair few times to maintain a good relationship with all the teachers around. It was clear to some of the teachers that he had taken a liking to you since he would sit with you during lunch often, but you didn't think much of it. It was a fine October morning in the school when it was your birthday, but what you didn't know was that Erwin had planned something small but intimate for you after school hours. He came by the Social Sciences faculty room and coincidentally, you were alone, checking and grading papers. "Good morning. Can I come in?" He asked very sincerely. You nodded your head and he entered. He smiled at you,- "Happy birthday!" You smiled in return and thanked him. "May I take a seat? I just wanted to extend an invitation to you for something special after school hours get over." You were quite curious to know about it and tried probing him when he said,- "It's a surprise. Can you meet me outside the school gates? I want you to see something that you are sure to like."
