Tired

For real
how does one define being tired, is it in your ability to do stay awake when you want to sleep or do you think it has to do with driving your car and not realizing when you get to your destination. Being blessed sometimes God sends his angels to guide us so that we don't run into trucks. At what time does one decide to just stop, i think i will sell my timeshare cuz right now i really just want to sleep.
