Laughing in his Sleep

Daryl did something really funny in his sleep last night. I woke up suddenly at about 4.30am due to Kel's incessant coughing. Then I heard Daryl's laughter. The funny thing is, he only laughed after Kel had coughed. So it goes like, cough, cough, cough, hahaha, cough, cough, cough, hahaha... It was so funny that I woke Kel up to witness it. Kel didn't believe me when I told him about what his baobei did. He asked me to go back to sleep as we are going to have a very busy day today. So I asked him to cough & see what is Daryl's reaction. After he coughed, Daryl would laughed. This happened a few times!! Kel was really convinced then. He remarked that our baobei is so mischievous that he even wants to play in his sleep.
