I would drive around town blasting classical/jazz music while playing a vuvuzela. After a couple minutes of that, I'd walk downtown in my gaskmask and dress and chill in one of the waterfountains. I'm actually pretty content with my life, though.
I would pack my drawing stuff jump on a random train and get out at a random station, there I would just start drawing some beautiful architecture, and maybe some interesting looking people. I would take the next train and go on and on until it gets dark and then I'll simply lie down and watch the stars before going home ^^
Daaamn even my fantasies are about drawing >.> How lame XD
Shop take a bath, read a book just about anything. When my sons where really young about once a month I'd get my husband to take the boys and tell them to go away for four hours. Four wonderful hours alone
