When he thinks I'm sleeping

Jake works 2nd shift, and now that it's summer, he's ALWAYS working late because there is more stuff going on in the streets, and more reports. I am almost always sleeping when he gets home. Sometimes he "talks" to me, but I am so sleepy that I have no idea what he says, or can't remember it the next day. So when I wake up the next day & ask him, he always laughs and just says he can't tell me. One night I actually heard what he said...he apologized for being grumpy lately, and he told me he loved me so much. I pretended I was asleep, but I smiled to myself, knowing what he actually said. He's super sweet when he thinks I'm sleeping!
