One of my Kindergarteners sent me a note w/ a sweet pic of
the two of us and my cats. I tried doing a Golden Retriever, but I need more work on that, so she's getting a beach instead.

...I came across a few days ago while sorting thru many piles of accumulated paper. Written by my now 27 year old, probably in first grade, based on the spelling. It has a rather haiku feel to it.

I also have a painting he did in daycare when he was about 2 1/2. The technique was the "paint something on one half of a page and then fold it over to make a mirror image." It sort of looked like an apple - a large red circular blob with a green stem-looking thing on top. I committed one of the terrible sins of parenthood, and rather than saying, "Tell me about your picture," as we are supposed to, I messed up and said, "Taylor, what's that a picture of?" A classic concrete 2 1/2 year old answer -
"It's a picture of paint." 
It is a treasured memory.
