Remember teacher appreciation day?

It comes around every spring, and many students give thank-you notes to favorite teachers, or maybe some flowers. But an anonymous former student of Lindley Elementary School in Greensboro, North Carolina, went the extra mile.

First, principal Tracy Root had all the teachers assemble in the auditorium, where she informed them that the unnamed former student, out of gratitude for the work they all do, had give each teacher a voucher for a free vacation for them and their families anywhere in the continental United States. The vouchers have a combined total value of $96,000, and the teachers were thrilled.
