I have really bad sleeping problems, so my bed is more storage space than a bed most of the time. I will change my bedsheets when I've shifted this damn cold. I have phases of caring about my bedsheets, most of the time I don't care too much. But if I'm feeling down I use my Peanuts bedsheets.
I think I can count on one hand the amount of times I've made my bed in my entire life.
