Hm...cloudy day...not really the temperature for a chillout in the park (and my horrible english-grammar :P ).
So...first step this day, take a shower and start to look like a human.
Next step: search a good location to calm down from the stress of the Week.
Third Step: Crap a coffee, enjoy the sight, have a nice day :)
So...use the Sunday, make it sunny by yourself, free your Soul on Viking Style:)
