while I'm deep in revision/rewriting/editing mode, a drain backs up (there goes time taking buckets of water to the other sink), the dishwasher develops a problem (and the kitchen sink drains into the stopped-up driain, so washing in the sink's an issue, too) and I get a cold and ARGH!
Folks who think being self-employed is a cakewalk of joy? Not so much some days. I can't ask somebody to fill in for me for a few minutes/half hour/call in sick.
So, back to work I go, even though it's 8 p.m. I've got chapters to fix before I (try to) sleep.
