The first day of school is always filled with anxiety.

That's something this boy couldn't hide.

Earlier this week, Los Angeles' KTLA asked four-year-old pre-K student Andrew Macias if he was going to miss his mom while in school. He said no and gave a smile, which quickly turned into tears.

You can bet there are thousands of other kids like Andrew out there going back to school -- you know, they're trying to be brave, but are frightened of the uncertainty that lies ahead.

Andrew's mother gave him a hug off camera because moms make everything better. That should be the first lesson Andrew's class learns this school year.
