Eli was excited to see Patrick leave. Patrick started a week earlier than Eli, even though they're at the same school, and Eli was completely nonplussed, perhaps even a little glad, to be missing a brother all day long.
Here was Eli's first day - he started preschool! He loves his teacher, Mrs. Kim. It seems ridiculous that he is in preschool, he seems so very old to me! Maybe it's because the word "big" is often used to describe both size and level of maturity - both "you're so big, you can reach that tall shelf" and "you're so big, you know how to write you name!" Since Eli is so big physically I think we "big" people tend to get confused about his maturity. I think of him as Patrick's age, as they are the same size and share everything, so this is just one of those helpful reminders to me that I shouldn't actually treat him like Patrick; they are 2 years apart, and 2 years is a lot when you're 4 or 6.
