When Karl's first day at tuition class he is only one student at that time. But, day by day he is familiar with this empty environment. One week later, Onar has joined the class, and there are no empty places. The teacher introduces Onar to Karl, and Onar immediately comes to Karl's sit and shakes his hands and says "Nice to meet you, Karl, can we become friends? ". Karl happy to see and said "Yes" immediately and later both studies together and goes home together.
Next month, there are also new students are joining. Karl wants new friends and his thoughts if a new student joins then immediately friends with him. The next day, he visits early as possible with extra preparation on how to talk and be friends.
The teacher and the new student are coming, as Karl and Onar stand straight and welcome the new student but, Karl and Onar both stopped because they imagined the new student is a boy but nothing but a girl. She introduces her name as 'Pearl', we want to introduce ourselves, but we both are shy in front of her, and on behalf of both introductions, the teacher introduces us.
The most embarrassing welcome of the new student.
