Those blocks are wonderful. Every time you look at them they will remind you that you made an impact on so many young lives. Good luck on your new job. All my kids have had a least one teacher or teachers aid who touched their lives and made an impact. My son still visits his special teacher who has since become his friend. Its hard to leave the kids you care about, but think of all the new kids you can reach. You are a special person with so much to give. I wish you the best.
