National Teacher Day, which honors teachers and recognizes the contribution they have made, is celebrated on the Tuesday of the first full week of May in the United States.

One day isn’t enough to show appreciation for all that teachers do. When you think of the hours teachers spend preparing lessons or grading papers, the out-of-pocket expenses, the days that never end, the ones who protect their students, the ones who went through a neighborhood devastated by Superstorm Sandy to bring supplies to families of their students and the community, or the teachers who wouldn’t leave school on 9/11 until every student was safe with his or her family, then you will realize that one day is hardly enough to say thank you.

The biggest thank you a teacher can receive is the smile on a child’s face after that child has gained understanding or the adult who comes up to you years later, now a teacher herself, and tells you that you made a difference in her life. Now think back and I am sure you can remember that special teacher and say thank you in your heart.

My daughter Melissa Wadler attends Midwood HS at Brooklyn College. In my opinion, teaching is one of the most noble professions that influence the lives of young individuals for a long time. Teachers are mentors who provide more than the academic excellence that comes with books. I am writing to thank all the teachers at Midwood HS who have a great impact on their students.

Thank you so much for being so powerful and for not taking that responsibility lightly. I am sure there are days that cause you to question if any of your work is making a difference and I want to assure you that your vast power of influence is making that difference in my daughter’s life on a daily basis.

A teacher can compel a student to have a lifetime hunger for knowledge. A teacher can inspire values of compassion, philanthropy, hard work, bravery, integrity and commitment.

Thanks to the administration and staff at Midwood for your contribution to making it such a great institution.
