Just returned from doing a school visit. After doing several sessions, it was a bit tiring, but exhilarating. After the presentation, there is a segment on the writing process followed by a question-and-answer session. The students really enjoy this as they get to ask the author anything and everything. They get so enthused that we usually run out of time before all the questions are asked.
Since today was Author Day at the school I visited, the students had a parade in the morning. They dressed up as favorite book characters. Even the teachers and the school staff joined in the fun, dressing up as well. It always feels good being part of a school event. That's part of the fun of being an author.
