Micah a sleep at the handlebars

This weekend Micah and I went for a bike ride. We attached his bike trailer to my bike and off we went. We had been riding for about 2 miles when Micah said he was tired. I told him just a few more minutes and we would head back towards home. As we were heading home I felt the bike jerk a few times, so I looked back and Micah was a sleep! I couldn't believe he was still holding on to the handlebars. I got him to wake up and we sung the alphabet together till we got home. I guess when he said he was tired he meant he was sleepy. I thought he was just tired of riding the bike. Next time he says he is tired we will head straight home.
