I'm self employed (well, we call it autonomo in Spain and it's a little different). The plus side is I can make my own schedule. The downside is I can get drunk/high on a school night.
My ex used to find out whether she was free at the weekend on a Friday night (lots of last minutes trips away too)........ Drove me fucking mental... Could never plan anything and people eventually stopped inviting us to stuff cos we were so non-commital.
