Ha was making his bed

Ha is a messy person (well, now, he's much better than before. When he was younger, it's almost impossible not to step on his things when going into his room.); however, he insisted in making his bed every night. In winter, he had 4 or 5 layers of blankets, and it would take him more than 10 minutes to make the bed. Now, he only had 2 layers, so it's much faster.

My question was: Every night, when I went to check on him at 11pm, most of the time, he kicked off all the blankets. Then, why bother to make the bed so neat?
