It's your son's preschool party today. Your 5-year-old boy is sitting next to you, waiting for the teachers to call his name for the ceremony. After that, he will perform a special show with his friends and sing a song.

The boy looks a bit nervous as he gets ready, even when you tried to reassure him many times.

"Mom.." the boy mumbled “I am.. nervous..” he continued, fiddling with the hem of his shirt and keeping his eyes down.
