Fridays for me are the same as every day except Wednesday, as I only go to office once a week at the moment.
I have no one to bother me, as long as i do my work then I'm pretty much left to my own devices, which is pretty great.
But I don't like distractions when I'm working so I leave tv etc off except for lunchtime. Every day is pretty chill and goes quite quickly if I'm busy.
