"Don't die"

On Sunday, Lex started to ride his bike with no training wheels. Now, we've been working on him starting by himself without our help. While I was upstairs today, I was watching Lex and Nate in the backyard. Lex was asking Nate to hold the back of his seat, which Nate did willingly. A couple of times, Lex fell over and he, surprisingly, did not get upset with Nate. He just kept explaining how to hold the bike. After a few times, Nate said, "you can do it, Yex, just don't die." Oh, to see what goes through his mind.
