Light at the end of the tunnel

So. you know those days when you feel as though your work is in vain, nothing has been known, and you wonder why am I doing this? Well, today I got my answer.
It was 2:00, 30 minutes before we dismiss for school. I was called to the office along with 2 other teachers. We sat down with our principals. At first, I was extremely worried. We were told to pack our things and go home. My first thought was that I was being fired. My heart just dropped; however, they then told us that they had been observing each wing since school started. We had shown something special, and so they were letting us go home early as a gift to us.
I do not need constant rewards for what I do. God placed me here, I will do my work, and I do love it. I do not expect to be given something whenever I do something good, because I believe that is what I am meant to do anyway. But, it sure warmed my heart to know that they recognized what I had been trying to do. And I pray I continue to do whatever it is they are seeing in me.
