3 out of the 5 working days, laways on the weekends. Sometime, well almost all the time, I'm running atleast 15 mins late in the morning so I'll skip it every now nad then. When I get home I see no point in making it since I'll go to sleep in a few hours anyways.
When I first moved out I had an ingenious plan that worked OK for a while. I would just sleep on top of the sheets with a comforter covering me, the bed was never unmade just had to be straightend out a bit and I only had to fold the comforter.
