Early reader

Miles has been able to recognize signs on stores for at least a year or more now. He knows when we are at Fresh and Easy, Costco, Home Depot, Smiths etc by the logos and locations more than actually being able to read. But yesterday he actually read his first sign at a building. We were going in the rear entrance we never go into at the movie theater at Aliante to see Puss in Boots. He looks up above the door and starts to sound out the one word posted large. Cuh, cuh, sssss, sssss, eheheh, no, no, no. CASINO!! "mommy, that sign says Casino". And it did. Not a logo or anything, just some letters making a word over the door.
I don't know whether to be proud or shame.
