How often do you pull a sickie?

I’m not talking about genuinely being sick – I mean those days where you wake up and just think nope. Or maybe you’ve got something else you’d rather do that popped up last minute, and work just isn’t it today, or maybe the weather is too nice to waste indoors

Do you feel guilty about it, or is it just part of maintaining your sanity? Also, what’s your go to excuse when you’re faking it?
