I want to be sick for a week
Why would you want to be sick for a week?
I'm going to enjoy being a couch potato
It is completely valid to sometimes want to be lazy, but getting sick can really hurt you for weeks or even months. Are you really sure you don't want to just call off without being sick?
I would rather be sick.
Yeah, I hear you, but did you think about how much pain you might feel with the sickness? Wouldn't it be nice to avoid all of that?
