Excellent Teacher

I was over at my friends house and she has a cousins that are Mexican.  They are the ages 14,19 and 3.  The littlest one was learning his colors so I thought I would help.  They speak no English at all.  We got his book out of his mom's bag and I pointed to colors.  It was so cute because he would yell out the color in Spanish and we would laugh and he would hide his face because he was embarrassed.  Some of the colors he needed help saying and didn't know very well.  One was amarillo, he couldn't get yellow at all.  I wanted to teach him the English words of the colors but I didn't want to confuse them.
